Fiber lasers in the medical industry

Fiber lasers have had a major impact in a variety of areas, including fundamental research, molecular detection, laser surgery, and biomedical research. Experts are making further progress in a number of studies using modern fiber laser technology. It is used for mid-IR laser spectroscopy, photodynamic therapy, etc.

In this article, we will look at the applications of fiber lasers in these two areas of medicine.

The current trend is to find the best applications for fiber laser systems, as for any other medical equipment. Firstly, they provide pain relief for patients during treatment. In addition, advanced laser modules increase the effectiveness of treatment. For maximum efficiency in the shortest possible time, high-precision laser beams are used. The ability to perform delicate procedures, minimal scarring and fast recovery are other benefits of fiber lasers.Fiber lasers for the medical industry

Fiber lasers for the Mid-IR Spectroscopy

Mid-infrared spectroscopy (or mid-IR) is a standard, non-destructive method of chemical analysis used in the laboratories.

New biomedical applications are of great importance due to the rising cost of healthcare and the need for rapid and non-destructive measurement technologies. In resource-constrained environments, compact designs of mid-infrared laser modules play a critical role in biomedical sensing applications.

The characteristics of fiber lasers, including benchtop applications, make them particularly suitable for biomedical applications. They provide high power spectral density and thus a high signal-to-noise ratio (SNR). And with today’s technology, final measurements are available in seconds.

The advancement of fiber laser systems has improved the clinical environment and treatment outcomes.

Fiber lasers for diabetes monitoring

Glucose monitoring in diabetes is one example of mid-infrared spectroscopy.

Glucometers are among the most widely used wearable biomedical sensors. Glucose monitoring is a necessary part of a patient’s life. They can do it either with the finger prick tests or with glucose monitoring devices worn on the body. Due to degradation, both types of devices have a limited lifespan. Mid-infrared spectroscopy can overcome some of the measurement problems. However, it can also face other difficulties.

According to modern technology, the process goes as follows: the device is placed on the patient’s skin, a flash lamp is activated, and broadband radiation is directed through the transmission fiber channel into the patient’s skin. Scattered and reflected optical signals are fed through the receiving optical fiber channels and interference filters to the arrays of CCDs. Then specialists see the information on the display.

Fiber laser systems for photodynamic therapy

PDT, or photodynamic therapy, is a treatment that uses a drug and the light of a laser beam to activate the drug. It is particularly effective in the destroying of cancerous and precancerous cells of various types including those of the lung, skin, bladder, brain and more. When it comes to cancer treatment, photodynamic therapy is used in the early stages under observation through the endoscope. Certain photosensitizers are also applied for treatment of other diseases such as bacterial, viral and fungal infections.

Common information about photodynamic therapy

Photodynamic therapy is usually used as a local treatment, which means it affects different specific parts of the body. The affected part of the body is irradiated with a laser beam from a fiber laser. Then, when exposed to light, a form of oxygen is produced that kills the cancer cells.

The custom PDT process includes 2 main stages:

  • Introduction of the photosensitizers into the body;
  • Light exposure.

The interval between these phases can vary from 10 minutes to 2 hours, depending on the disease and its stage. There are different methods of light exposure. It depends on the localization of the pathological project:

  • Direct light exposure;
  • Endoscopic light exposure;
  • Intraoperative light exposure (during surgery);
  • Intravenous light exposure (blood photomodification).

PDT for use in ophthalmology

In ophthalmology, fiber lasers are used to treat certain eye diseases when we talk about PDT applications. For example, they are most commonly used in the treatment of age-related macular degeneration (AMD). However, its role today remains quite limited. With this method, the photosensitizers are injected into the vein. They selectively accumulate in abnormal blood vessels. The low-power laser beam then activates the light-sensitive drugs. The drugs destroy or seal the abnormal vessels without damaging the other cells. Specialists consider photodynamic therapy as a way to slow the progression of the disease and preserve vision.

As the use of fiber lasers continues to grow in various medical fields, we can say that laser modules have proven to be effective. They have been instrumental in developing of a wide variety of fiber laser systems and obtaining useful theoretical and experimental results. This is especially true in the medical industry, where fiber lasers are widely used.

This article will discuss several scientific spheres where fiber lasers have found their applications.Fiber lasers for scientific purposes

Fiber laser systems’ requirements

Research and scientific fields need correctly designed and specialized equipment. Fiber lasers have to comply with the specific requirements due to the environments, taking into account the fact that laboratory conditions can differ from the real ones. However, scientists are always calculating situations that are close to reality, taking into account maximum permissible errors or tolerances.

Laser modules have all qualities that are necessary for all laser applications whether for industry or for laboratory. For example, operation stability and remote control provide high performance rates for any specialists. Moreover, fiber laser systems are easy-to-use in achieving scientific purposes in comparison with other devices.

Fiber lasers in atom cooling process

Fundamental physics has gained many opportunities due to the ability of cooling atoms to ultra-cold temperatures.

Cooling of the molecular gasses with fiber lasers is a challenging process that is difficult to perform because of the molecular structures’ complexity. The lastly developed technologies of the molecules cooling have made it possible to improve their precise control that results in making the interaction processes better.

Thus, fiber lasers systems have a great impact on this field of research. The understanding of the molecules’ interaction has allowed specialists to put chemistry reactions under control. Moreover, it has influenced the advancement of quantum materials.

Ultrafast fiber lasers for nonlinear optics

Ultrafast fiber lasers are used as a part of the multiphoton device for a number of spheres, including multiphoton microscopy, dual-comb spectroscopy, etc. A multiphoton microscope is a device that exploits the principle of nonlinear optics to create contrast in a sample. The multiphoton technique applies the nonlinear optics for samples’ imaging and making 3D images. Due to these processes, specialists have achieved better 3D imaging.

Along with the scientific research activities, this technology is especially beneficial in medicine where it helps in diagnosis of diseases and identification of material properties. Thus, it is applied for identifying various types of cancer, for example, for esophageal and pancreatic cancers.

Fiber laser systems for plasma physics

The majority of studies related to atomic physics are based on the interaction of two components: atoms and light. Fiber lasers have become a usual instrument in experiments of atomic physics. All questions connected to nuclear fusion processes such as nuclear reactions that occur in plasma, development in laser ion sources have received a great interest due to the gaining potential of this technology.

In plasma physics technology fiber lasers are applied as parts of plasma accelerators. Plasma accelerator is a sophisticated device that applies electric fields developed in plasma waves excited by intense fiber laser pulses. Such types of accelerators have proved to be extremely space-saving sources of energetic particles and radiation.

Plasma qualities depend on a number of parameters that are participating in its creation. Laser modules’ characteristics, irradiation conditions and the target parameters create the certain processes occurring in generated plasmas. It is also important to monitor the plasma condition constantly due to its short life. The specialized detectors provide full details of plasma characteristics, including its density, temperature, etc.

Fiber lasers have greatly contributed to plasma accelerators’ production. So, they have found their implementations in high energy physics, biological and medical sciences, etc. And there is still space for further research and innovations.

In recent years fiber lasers have proved to be an essential part in scientific fields, including the above-mentioned applications. The evolving role of science in many spheres demonstrates the growth of interest in scientific research activities of fiber laser systems.

Fiber lasers for research and development purposes

Fiber lasers have shown themselves as powerful and effective instruments in various areas including medicine and science. They have also found their place in aspects where there is a need for research and development purposes. For instance, for quantum computing development.

The sophisticated calculations of the quantum computers have become possible due to the photons. In quantum computing, the basic unit of data is called quantum bit, or qubit. In comparison with the traditional bit, qubit can store multiple values at the same time. In the future, specialists are going to combine many qubits together to make better computational power.Fiber lasers for research and development

Fiber lasers for quantum computing

Fiber lasers have become one of the main technologies for creating the up-to-date quantum computing architectures. This field has reached unprecedented heights by improving quantum software and hardware technologies.

Sophisticated fiber laser systems play a crucial role in quantum equipment development. Specialists are interested in improvement of the laser modules that will suit quantum calculations due to their advantages. They appreciate fiber lasers’ qualities such as high levels of accuracy and control, compact size, etc. Furthermore, they are able to become parts of more powerful and complex solutions.

Techniques of the qubits creating

Nowadays, specialists have learnt how to apply good, reliable qubits with the help of trapped ions. Scientists have found many benefits of their applications. Trapped ions are easily managed and can interact with the nearby neighbors. They provide high rates of fidelity and relatively long coherence time that means the qubits are long-lived. Moreover, they can perfectly match other trapped ion qubits to make quantum algorithms.

There are at least ten methods that are usually applied for creating qubits in quantum computing. Here is a list of a few of them:

Creation qubits with the trapped ions

Why do specialists apply ions meaning charged atoms as qubits? The leading cause is that they can be trapped at the precise location with the help of electric fields.

The first method of the qubits creation with trapped ions is effective technology for quantum computing. The qubits are created by encoding quantum information in the internal states of charged ions. With the help of a fiber laser, the cloud of ions is created. When ions are cooled, they can be trapped with the usage of electric and magnetic fields. Due to the fiber laser proper configuration, specialists can produce robust qubits by encoding quantum information in the internal states of the trapped ions.

This type of qubits has more benefits in comparison with the other types, for example, high accuracy and low error rates. Moreover, this kind of qubits is perfect for manipulation and control of separate qubits and therefore for quantum computing.

Trapped ions are in the foundation of quantum computers. But they are further developing to become powerful for other more complicated devices in the future.

Creation qubits with the neutral atoms

The second method comes from neutral atoms that are applied in encoding quantum information in the internal states for creating qubits. Neutral atoms are relatively insensitive to environmental noise and have long coherence times.

For this method specialists apply a range of optical tweezers to trap and manipulate separate atoms. The tweezers are made with the laser beams focusing on a small spot. With the cooled atoms, there is an opportunity to trap the atoms in tweezers and then create qubits.

Due to this technique, specialists can provide reliable qubits considering the right frequency and timing of the microwave or radio frequency pulses during their creation.

Quantum computing with the help of precise fiber lasers have become an important instrument both in scientific and industrial fields. There is no wonder that they are so widespread due to their physical abilities and simple operational principles. These technologies, along with fiber laser systems, are already well-developed. Producers are constantly looking for a range of new viable solutions that will allow the use of quantum computing in other directions around the world.

Fiber lasers’ popularity increase is a result of their end-use benefits, such as reliability, usability, operation stability, etc.Fiber laser systems for multiphoton microscopy

What is multiphoton microscopy?

Multiphoton microscopy is a laser scanning microscopy method. In this technique there are as little as two or three photons. They are combined to generate high resolution 3D images of microscopic samples.

Laser microscopy has turned out to become an instrument in material development and studies. It is mostly applied in biological sciences and tissue engineering. Scientists use it for imaging of living biological tissues that can be conducted due to different scales whether on the molecular levels or through the whole organism.

During the experiments, multiphoton microscopy (MPM) is able to provide the most accurate measurements of the biological activities. Measurement procedures can last from several seconds to weeks, or even months that would cause some discomfort for patients. In these cases, minimal invasion plays a crucial role for them, besides, providing the most precise results.

This far-field imaging is developing rapidly and demands more complicated contemporary fiber lasers. The further progress will expand the capabilities of multiphoton microscopy in observing biological processes within deep layers of living tissues with minimal damage.

Fiber laser systems in multiphoton microscopy

As for multiphoton microscopy, fiber lasers are essential elements of this technology. Compared to usual lasers, fiber laser modules have a range of advantages.

  • Due to the absence of a separate optical medium for beam delivery, fiber lasers are more stable and easier to maintain. They provide very high levels of optical gain.
  • In comparison with traditional CO2 lasers, fiber lasers have a higher power conversion rate, they are energy efficient.
  • Thanks to the highly focused narrow laser beam, laser modules can be applied in complex designs where there is a necessity in high precision.

Multiphoton excitation with the fiber laser pulses have given an opportunity to get the high-resolution images. With the increasing role of microscopy, fiber laser technology has also developed and proved to be the most suitable.

Neuroscience is one of the most modern research areas. Specialists study a variety of the neuronal networks to find out the nature of brain pathologies and create a treatment for neurodegenerative diseases. Nowadays, scientists have received an ability to analyze brain activity during the interaction of the brain and visual organs, carrying out some operations, etc. The observation of the brain operations is necessary for understanding of its functioning and pathological conditions’ appearance.

Deep brain imaging helps with these purposes. However, there are factors that should be taken into account during the fiber laser designing, for example, providing the proper volume. The problem is the deeper the penetration, the worse image quality. As a result, fiber lasers are the most suitable for neuroscience because fiber laser systems are power scalable.

Laser modules for spermatogenesis

Multiphoton microscopy makes the visualization of different biological processes in live tissues possible. For spermatogenesis multiphoton microscopy uses fiber lasers for visualization of all tubules with and without sperm.

As a result of the latest development, this technology of sperm extraction has replaced conventional testis biopsies. Nowadays, specialists are improving new technology and solving other challenges. Due to modern technology, the tubules’ retrieval relies only on appearance. So, in the future multiphoton microscopy has every chance to help real-time visualization improvement and apply it in clinical applications.

Nowadays, fiber laser systems participate in a number of various field experiments from triggering lightning in thunderclouds to genomics.Fiber lasers in flow visualization

Advantages of the fiber laser systems

A fiber laser is a well-structured compact laser that provides high electrical and optical efficiency. Fiber lasers are reliable and capable of delivering well-controlled and accurately directed laser beams. By amplifying specific wavelengths inside optical fibers specialists are able to design a fiber laser system with excellent beam quality and high peak energy.

Lasers are not intended to be light sources as illumination devices. However, they are good at light concentrating in space or particular wavelengths. The majority of laser applications can be divided into three segments:

  • the data transmission and processing;
  • accurate delivery of energy;
  • alignment, measurement, and imaging.

Fiber lasers have many significant advantages in comparison with the other laser types. Except for the previously mentioned high-quality laser beam and many other features, laser modules are powerful due to their high brightness. Fiber lasers don’t require any additional maintenance because optical fibers are set up without any mirrors and lenses.

Flow visualization with fiber lasers

Flow visualization is a technology that is applied to make the flow patterns visible for getting qualitative or quantitative data about them. This method is to observe the behavior of particles in the air stream. Lasers help to see the direction and uniformity of the air flow.

Particle image velocimetry (PIV) is one of the technologies that refers to the flow visualization. It has received great popularity in a range of scientific and engineering spheres. PIV technology is required when there is a necessity in measurements of various fluids and gas characteristics, for example, instantaneous velocities.

A custom PIV system includes a multi-pulsed fiber laser system, at least one camera synchronized with the laser, and a computer to display the received information.

Specialists can apply CW or pulsed fiber lasers in the acquisition process of PIV data. Fiber lasers are used because they are highly powerful with short pulse durations. Fiber laser modules make small implemented tracer particles visible. With the flow of the fluid, they are moving at the same pace. Then with the help of a camera a series of photos is taken which are used for further calculations of particles’ speed or direction.

Applications of the PIV technology

Due to its capabilities, particle image velocimetry has found its applications in many fields where highly macro and microscopic scales are used.

As any other fiber laser-based application, PIV is a technology that requires highly reliable laser modules. In reality, they have to operate in harsh environments that bring some difficulties outside the lab. That’s why specialists are mostly interested in creating robust and cost-effective laser modules.

Particle image velocimetry systems are proved to be valuable instruments. They are applied in a range of industries, for example, in aerospace, agriculture, medicine, etc.

Here are some more detailed examples of applications that fiber lasers have as PIV technology components.

Automation and quality control processes for gas and liquid production. PIV technology based on the most modern methods can be applied for the simultaneous measurements of the velocity and turbulence fields including gas and oil production.

Measurements and analysis of the indoor airflow fields. It can be complicated to measure a complex turbulent flow field accurately. That’s why the PIV technique is used to meet these challenges. A number of studies have demonstrated this technology’s effectiveness and named it one of the most universal instruments for measuring. Depending on the scientists’ purposes, they can choose a range of parameters for measurements. Despite some limitations for PIV systems, the obtained data about indoor flow is essential for validating numerical simulations and analyzing.

Combustion diagnostics. PIV technique has become an advanced instrument for combustion constructions. Its optimization, including improvement of the in-cylinder flow structures, is necessary due to new emission regulations focusing on reduction of pollutant formation in engines. When we are talking about combustion diagnostics, there are some challenges. Due to the engines’ structure, it’s complicated to analyze any changes.

PIV technology in medicine. In addition to the technical measurements, PIV has been widely applied in evaluation of the medical devices’ performance, for example, of the blood pumps, artificial heart valves, etc. It can also make predictions of the blood damage potential that different medical devices have. This technology mostly depends on the quantity of the images, their resolution and quality.

Nowadays, PIV technology has proved to be effective, and specialists are still looking for new ways of its applications for various systems. Fiber lasers, in turn, have played a great role in its development thanks to their advantages compared to the usual production equipment.

If it comes to the field of science, fiber laser systems are applied in medical sciences, biology, micromachining, etc. Fiber laser is in many ways the best solution for professional engineers and researchers for their projects’ development.Fiber laser systems for science

The most general characteristics of the fiber laser systems

The top quality of the laser beam, great performance and power efficiency have helped fiber lasers to find a place in many areas of scientific and biomedical studies. Fiber lasers imply an ultra-narrow linewidth and reliable working operation thanks to the short cavity length and phase-shifted design.

The single-frequency fiber lasers are perfectly fit for various applications due to the various ranges of frequency or wavelength. Such applications include, for instance, optical trapping and atom cooling. The other parameters of laser modules, like compact size and low noise, make it possible to use it in interferometric sensing.

Laser engineers and scientists are constantly looking for new opportunities for the fiber lasers and developing more sophisticated technologies.

Types of fiber lasers due to their parameters

Fiber laser systems can be classified due to many categories, but there are parameters that play a crucial role in operations. These features are listed below.

  • Laser power. High-power fiber lasers provide more energy and operate faster in comparison with low-power lasers. Laser power is measured in watts.
  • Mode. This parameter relates to the core’s size in the optical fiber. There are single-mode and multimode fiber lasers. The single-mode lasers have a smaller diameter of the core and transit laser light successfully and at the same time providing a better laser beam quality. Multimode lasers have larger diameter in comparison with the single-mode ones.
  • Laser source. Lasers can also be varied considering the applied material of the laser source. There are thulium-doped fiber lasers, erbium-doped fiber lasers, ytterbium-doped fiber lasers, etc. Each of them has different wavelengths and fields of application.
  • Operating mode. The difference of fiber lasers depending on the operating mode is connected to the way the laser beam is released. There are usually lasers with continuous-wave or the pulsed mode. The pulsed lasers have the short pulses that are released at an established repetition rate. While in the continuous-wave operation mode, a continuous laser beam is released. Simply put, its amount of energy is at the same level all the time.

Fiber lasers for science in short

Fiber lasers are considered to be a unique technique suitable for many applications that can be combined into one sphere called the science.

Talking about science, laser modules perfectly fit for biophotonics, multiphoton microscopy, neuroscience, etc. From the date of creation, a fiber laser has been applied as an instrument for research in astronomy, physics, biology, chemistry, etc.

  • High energy physics;
  • Attosecond science;
  • Ultrafast X-ray science;
  • High harmonic generation;
  • Femtosecond chemistry, etc.

The ultrashort pulse fiber lasers allow conducting scientific and medical research in different fields. The fiber laser systems with the mid-infrared wavelength range provide the analysis of biochemical content of tissues.
Here are some other spheres where fiber lasers are applied.

Fiber lasers for SFG spectroscopy

One of the applications of the fiber laser systems is SFG spectroscopy. Spectroscopy provides detailed data on the molecular level about the structure and molecular groups by studying the atoms’ vibrations.

This technology outperforms the traditional methods by the means of good qualities like vibrational specificity and surface sensitivity. In this approach laser beam quality is important because it generates the SFG signal. Due to spectrometers’ abilities to effectively provide precise measurements and vibrational spectroscopy studies, they are often applied for chemical and biochemical laboratories, as well as for the studies in physics, material science, etc.

New approach for fiber lasers in plasma physics

In plasma physics scientists have recently suggested a new way of working with high-power lasers for the accelerators. They have got an idea of combining the lately developed laser modules with laser-plasma accelerators.

The fiber lasers are fast and compact. That helps in the creation of compact and well-managed accelerators that can be applied in various related spheres, like high-energy physics or biomedical treatment. The researchers are planning to use an intense laser beam fired through a gas to generate a plasma wave.

Ultrafast fiber lasers for optogenetics

Fiber lasers have also found another application in the specific sphere of neuroscience called optogenetics. Optogenetics is a field of biophotonics. It is a recent approach that has provided new opportunities for brain study. Due to this technology, researchers can study the neurological activity in particular cells of the brain. The research and studies in this field will assist the developments of treatments for neurological and psychiatric disorders.

The concept is to use fiber lasers for the exploration of the brain’s neural network. Scientists study it with the help of the light that activates or inhibits signaling of neurons in the brain. Fiber lasers provide the necessary laser beam quality and accurate modulation. Moreover, laser modules are compact and cost-effective which makes them easy to use.

Fiber laser systems possess some benefits over the other lasers that’s why they have more and more applications in different scientific areas.

Fiber lasers and their applications in medicine

Fiber lasers have received much attention because of their qualities, benefits in use and a number of applications in various spheres. A range of the different wavelengths allows specialists to use fiber laser systems in factory environments for welding, cutting, texturing, etc. At the same time, the ultraprecise fiber lasers are applied in spheres where accuracy is a crucial feature – for example, in medicine, micromachining or scientific research.Fiber lasers and their applications in medicine

History of the fiber lasers’ development

The history of the fiber lasers’ evolution began with the invention of the first laser in 1961. First lasers didn’t achieve great of popularity from the very beginning, as they were complex and quite expensive. Fiber lasers got serious commercial applications only in the 1990s. The main cause is the gradual development of the fiber laser technology.

Today, fiber laser technology is still improving, creating more powerful and efficient fiber lasers. Specialists are working on the lasers’ accuracy, lasers’ environmental impact, etc. More improvements were made when the outputs of multiple fiber lasers were combined. This modification has led to the improvement of the power and range of the laser beam.

Medical applications of ultrafast fiber lasers

When it comes to fiber lasers’ applications, ultrafast fiber laser systems are applied in various spheres. However, there are fields where fiber lasers are irreplaceable, for instance, in medicine.

Fiber laser technology has made a great contribution to the growth of medicine. Fiber lasers are applied in fields ranging from therapy and ending with surgery. Thanks to the tremendous demand for healthcare, fiber laser technology has grown into a mature industry by making new innovations. Fiber lasers have rapidly adapted to the medical procedures’ evolution, considering their high-power densities in sterile noncontact processes and providing cauterization.

Fiber lasers in photodynamic therapy

PDT or Photodynamic Therapy is a treatment where the fiber laser light is used to destroy abnormal cells. From the very beginning, this technology was specially developed for the cancerous and precancerous cells in oncology. Moreover, it was suitable just for the particular cancer types.

The further development of PDT demonstrated that it can also be effective for general oncology and other kinds of cancer. This method is more convenient for the patients because it represents a noninvasive or minimal invasive alternative technique and provides less time for the recovery.

Fiber lasers in dentistry

The other medical field where fiber lasers have been applied over recent decades is dentistry. Fiber laser systems have proved to provide a fast and easy way of treatment. Fiber lasers have offered a significant reduction of the pain during or after the treatment for the patients. Moreover, the time required for the procedure itself and for the recovery period has got shorter.

Fiber lasers’ requirements in this sphere can be diverse starting from the essential laser characteristics like the wavelength and ending with physical qualities like size.

Fiber lasers for optical coherence tomography

From the very beginning, optical coherence tomography was developed particularly for ophthalmology. Meanwhile, today optical coherence tomography has found many applications in medicine.

The laser beam light is applied to take the cross-section images for diagnostics in clinics. The good resolution of the image helps in finding tiny infections at a few millimeters depth at the early stage. It is applied for diagnosis and treatment of diseases, monitoring of the therapeutic efficacy and different processes.

Fiber lasers for aesthetic applications

Laser modules have also become necessary instruments in some aesthetic, cosmetic or dermatology procedures. Previously, the CO2 lasers were produced for these purposes. However, due to fiber lasers’ recent development and advances, fiber lasers demonstrated their effectiveness as well.

The fiber laser systems are increasingly applied for performing radiation treatment on a patient. The fiber lasers are distinguished by their wavelengths, quantity of laser beams, design, etc. The wavelength can define a desired efficiency and depth of penetration for the treatment of the certain body part. The plurality of the fiber lasers may be placed next to one another to provide radiation along a line or located to achieve only the selected spaced areas of damage.

The most common fiber lasers applications in aesthetic procedures are skin resurfacing and tattoo removal. If we are talking about more complicated procedures, fiber lasers are applied for treatment of vascular lesions, skin micro-preparation, psoriasis, etc.

Considering all the progress that fiber lasers have already achieved over the past few years, scientists are still focusing on the development of more powerful and precise fiber laser systems. Fiber laser technology is applied by many specialists from different spheres for medical procedures and scientific research. Thanks to the fiber lasers advantages, they have become an essential tool for a lot of industries and spheres.

Fiber laser systems kill bacteria in the human body

Recently, scientists have developed new fiber laser systems that can kill bacterial superbugs and spores. The bacteria that can threaten human life get used to any medicine, including antibiotics. This fact made developers look for other ways of treatment. And for some applications, the alternative can be a special ultrashort-pulse fiber laser.

Fiber laser systems kill bacteria

Fiber laser modules’ effects

Researchers from the United States have discovered that fiber lasers that emit ultrashort pulses of light are able to eliminate bacteria resistant to drugs. Scientists explored the ultrashort-pulse lasers’ germicidal characteristics and found out that fiber laser modules are able to inactivate such bacteria and viruses without destroying human cells. They used the most common viruses and bacteria to look at the effect of the lasers on them. Among them are those which cause infections of the skin, or different organs, urinary tract infections, and wound infections. Researchers also took various types of spores that cause food spoilage and food poisoning. Some of them withstand cooking and boiling.

All bacteria and viruses include protein structures. The ultrashort-pulse fiber laser makes these structures vibrate until their molecular bonds break. As a result, there are incorrect linkages between protein structures that lead to a halt of normal protein function.

In fact, to achieve the desired results the scientists have to provide accurate laser power. To get viruses and bacteria inactivated there should be different laser powers. But if these power limits are higher, the laser starts killing human cells. So there is some power interval to destroy pathogens but reserving the human cells healthy.

Future of this fiber laser technology

Firstly, the developers see the future for this ultrashort-pulse fiber laser technology in inactivating pathogens and preserving human proteins and cells at the same time. With the help of this technology, it would be possible to disinfect a surgical wound with a laser beam, or even to treat bloodstream infections. Moreover, this fiber laser technology can be applied as a replacement for chemicals like bleach or radiation because they can be damaging to people. Ultrashort-pulse fiber lasers can become a new way to provide safety to various biological or blood products.

According to the results, fiber lasers have killed about 99.9% of the target bacteria and reduced their quantity by 1,000 times. Moreover, such fiber lasers don’t harm human cells that can be applied in wound sterilization or disinfection.
