According to recent studies, the global automation industry will greatly grow this year. So, manufacturers should constantly develop new ways to optimize processes and increase the quality of their products. They have to collect more precise information and improve automated identification systems based on fiber laser technology to advance traceability because the supply chains become significantly complex. 
Herewith, the choice of marking technology plays a crucial role in the realization of a traceability system. Marking systems based on fiber laser technology are the best solution for those manufacturers who require high-quality marks that provide conformity and accountability. The fiber lasers for marking arranges it by offering three important advantages: a high contrast, permanent marks, and adaptability to complex shapes. 
Fiber laser systems are especially advantageous at marking high-contrast engravings on aluminum and most other metals. Moreover, they arrange a high level of strength, integrity, and accuracy of the parts being marked.
In particular, it is recommended to apply fiber laser etching for the creation of high-contrast markings on aluminum. The surface of units is getting modified at a microscopic level. The laser beam emits an immense amount of heat to the material surface, melting and expanding it, therefore, producing a texture on the microsurface that results in transforming its color and makes a mark more contrast. Finally, after the long-term changes to the surface texture, the marks change and become permanent and resistant to any kind of damage like abrasion and scratches. 
Additionally, manufacturing parts are often repeatedly applied and can face severe operating environments and extreme temperatures. Marks made by non-permanent marking techniques like inkjets, dot peens, etc. can become deteriorated or difficult to read after a while. Fiber laser etching offers lifetime traceability and legibility of markings on units. 
Also, manufacturers can apply fiber lasers to print deeper high-quality codes that remain readable for a long time. The fact is that marked code passes deeper into the metal and has a rougher surface texture due to the disposed fiber laser properties. Fiber laser etching is widely applied in the automotive industry to prevent any kind of laser features are disposed to produce like sandblasting, e-coating, powder coating, etc.
Industrial fiber lasers for marking are systems with low maintenance, easy automation, long operating life, and do not require consumables.

2020 is known by the COVID pandemic and affects numerous fields of the market. The market of fiber laser systems is no exception. For instance, industrial laser systems remain relatively stable. Herewith, specialists even expect growth of the fiber laser market in 2021.
To be more precise, laser systems are regarded as “a solution seeking a problem”. Herewith, fiber lasers are widely used in numerous fields of technology. Even conventional things apply fiber laser technology: LED screens, computers, and smartphones.
Nowadays laser system’s price is constantly decreasing making them more accessible. “It started with small laser marking devices, today it comprises fiber lasers beyond 1 kW power.” Moreover, the number of manufacturers of fiber laser systems increases steadily decreasing the price of laser diodes.
The first trend in fiber laser systems includes quantum technology. The combination of quantum and fiber laser technology requires a lot of miniaturization and integration of tools. It should be noted that quantum technology uses laser beam pulses emitted by compact light sources.
The second trend supposes ultrafast material processing with ultra-short laser beam pulses. The thing is that ultra-short pulsed laser systems are the most popular ones on the market now. These fiber lasers are a type of solid-state lasers that produce very powerful laser beam pulses as short or even shorter than a picosecond.
Their property of high intensity allows breaking almost any material in short times. Nevertheless, they also have a disadvantage – speed limitation. Thus, ultra-short pulsed fiber laser systems still need some improvements. Additionally, researchers plan to increase laser beam power and even to apply multi-beam technologies for an optimal process. Such fiber laser technology is very promising for new applications.
Another trend is connected with researches on extreme laser beam light. Conventional fiber lasers do not achieve exawatt pulses, however, they reach world records in different parameters. Herewith, they continue aiming to ultrahigh intensities around the world. New records in focused intensity can be expected in 2021. Fiber laser technology plays a crucial role because a new generation of scientists enables to create a complex laser system and understand how to conduct experimental research with it.

Atom experiments carried out by the International Space Station suppose many preparations, herewith, integrated fiber laser systems are very important for this mission. Researchers plan to perform a cold atom experiment out of the laboratory and into microgravity.
To be more precise, these plans need large improvements in the following elements: laser systems, optics, and electronics. Herewith, these fiber lasers have to be compact and maintain the environmental challenges of a satellite launch. Therefore, fiber laser systems are considered to be very promising for space missions with cold atom experiments.
It should be noted that laser systems used for cooling and trapping have been presented by German researchers. Moreover, their partners promote fiber laser integration, while others provide electronics and other laser modules. The thing is that they use micro-integrated diode laser systems that are installed at the center for trapping and cooling atoms.
Additionally, “a standard diode-laser module as developed at FBH delivers more than 1 W at 780 nm out of a 40 g module.” The fiber laser system has been already tested and demonstrated a long lifetime of 100,000 h mean-time-to-failure. The laser system can withstand extreme temperature changes ( -55° to 85°C).
These diode-laser modules promote the development of complex fiber lasers for various experiments in microgravity. Laser systems with an external cavity offer a high level of spectral purity and stability. This type of fiber laser is installed into a master-oscillator-power-amplifier.
Herewith, it is possible to tune different wavelengths of these laser modules. Thus, they are widely used in a series of missions. The success of the whole experiment depends on the design and production of reliable, compact, and complex fiber laser systems.
Finally, this experiment is very potential. It is necessary to install several fiber lasers, the required optics, and control electronics for a significantly complex system. Moreover, they can be applied in smaller satellites. Such an integrated laser system includes a rubidium vapor cell for cold atom experiments.
The combination of fiber laser systems with an optical frequency comb allows applying them in small and simple vapor-cell-based clocks. The application of complex fiber laser technology, as well as monochromatic systems, advances the step-wise qualification of cold-atom experiments for space flights.

A high-power fiber laser has been successfully tested in field trials to weaken hard rocks to increase efficiency and reduce the cost of geothermal drilling. The fiber laser technology promotes a process applied to access geothermal heat — a clean and sustainable energy source.
The thing is that when drilling deep into the earth’s crust is performed, the temperature of the drill bit not only increases on average by about three degrees Celsius per 100 meters but also when it collides with a hard stone, the drill bit wears out faster and the speed of its penetration decreases. 
The cost of this process can be extremely high, and often prevents investors from continuing with deep geothermal projects. Therefore, a group of researchers from Germany combined with partners on a research project to develop a method for mechanical drilling of hard rocks employing a laser system. 
This fiber laser system can not only increase the penetration rate in geothermal drilling but also helps to maintain the cutting edge of the drill bit by loosening and even breaking the rock just before drilling begins.
To be more precise, the researchers have developed this laser system by initially installing a test unit with a ytterbium-based fiber laser with an output power of up to 30 kilowatts, which they then used to successfully loosen sandstone, granite, and quartzite. At the same time, all these materials are solid rocks with a strength of more than 150 megapascals — up to 80 percent. 
A jet of water is used to direct the laser beam to the rock surface – similar to how optical fiber can direct a laser system— which also prevents contamination and damage to sensitive fiber laser optics and makes it easier to remove rock fragments with a drilling tool. 
Then the engineers use a fiber laser system on the rig in a specially designed drill string and test the new tool in real-world conditions in field tests, which also proved successful. In future research projects, the researchers plan to further improve the laser beam power distribution and add digital sensors to the hybrid tool to get feedback from the drilling process and thus be able to respond to material changes on the drilling path. 
The flexible adjustment of the laser beam output power is one of the factors that make it a particularly effective tool for facilitating drilling processes. According to the researchers, the developed powerful fiber laser system will help reduce the cost of deep geothermal drilling in the future and simplify the use of geothermal energy as an inexhaustible source of energy-supporting other renewable sources such as sunlight, wind, and water.

Recently a team of engineers from the U.S. has created a microrobot that allows for directing a laser system within the body to perform minimally invasive surgery. The thing is that traditional energy-delivering tools are very complex compared to the new fiber laser. It is necessary to put them close to the target site resulting in limitations of accuracy.
Additionally, such laser systems can lead to unwanted burns in adjacent tissues and smoke appearance. Even though fiber laser systems are regarded as very promising solutions, they are required to meet additional requirements. Herewith, the direct application of current fiber lasers for minimally invasive surgery is limited by the following factors:

• the size of surgical systems;
• levels of accuracy;
• repositioning, steering, and manipulation.

The novel fiber laser system combined with the microrobotic end-effector can be widely applied in traditional endoscopic systems for application in minimally invasive surgery. The microrobot has a size of 6×16 mm and it provides high speed and accuracy and can operate with current endoscopic devices.
The team members claim that their fiber laser technology promotes accurate direction of laser beams at small target sites in complex patterns to advance minimally invasive surgery by laser systems inside the body. Such benefits as “a large range of articulation, minimal footprint, and fast and precise action” make novel fiber laser systems very potential to increase surgical capabilities in a plug-and-play fashion.
It should be noted that surgical fiber laser has to be both of the diameters of a drinking straw and relatively nimble. The operating principle of the microrobotic laser system is based on the three compact mirrors that fastly rotate to direct and redirect the laser beam in a compact surgical system.
Therefore, the microfabrication technique is used to make the system smaller. Herewith, this fiber laser technology offers a highly efficient fabrication process. The fiber laser has been already tested and demonstrated the high efficiency of microrobots in creating and following complex directions.
Thus, numerous laser beam ablations can be carried out with fast speed over a large range and a high level of precision. The team showed efficient performance of the fiber laser system by integrating it at the end of an endoscope. This non-disruptive solution enables the team to increase the opportunities of minimally invasive surgeries in the human body with life-altering or potentially life-saving impact.

Modern fiber laser technology allows for detecting a chemical transformation inside a cell live. Additionally, it promotes the production of microchips by printing paths in a thin layer. The latest femtosecond laser system makes all these developments real to achieve.
It should be noted that nowadays numerous laser beam sources are distinguished. Different laser systems have their own characteristics and fields of application. The novel fiber laser system emits ultrashort laser beam pulses, femtosecond ones. To be more precise, “this is the scale on which, for example, intracellular chemical reactions take place.”
It is possible to detect these reactions by taking a photo thanks to the new laser system. Moreover, the femtosecond laser beam source enables very accurate removal of materials from different surfaces without damaging them. The scientists claim that this fiber laser is even too accurate.
The thing is that some applications require nanosecond laser beam pulses (they last much more longer). Nevertheless,  conventional fiber lasers can not draw paths of accurately planned depths in ultra-thin materials, compared to novel laser systems. Strong laser beam energy located in a small area leads to melting the materials.
The novel fiber laser system operates firmly but gently. It is susceptible to mechanical disturbance, herewith, the laser system has a compact size and it is mobile. Fiber lasers have significantly helped the team to develop the system. The operating principle of fiber laser systems is based on an optical fiber enclosed in a ring.
The laser beam pulse passes inside the fiber without any mechanical disturbances. Herewith, it is possible to touch, move, shake the optical fiber not influencing the stability of the fiber laser. Also, this laser system offers a particular frequency at the output that makes the laser unique.
Standard laser systems use laser beam frequencies that are dependent on the length of the fiber optic loop in which the pulse passes. The solution is to reduce the circumference of the ring. Thus, scientists can control, change, and even duplicate the basic laser beam frequency.

Novel fiber laser systems have been developed by an international team of researchers to provide efficient detection of cancerous cells during the surgical process. The fiber laser is a part of a compact multimodal imaging system that enables testing tissue samples directly during surgery.
It should be noted that usually microscopes based on fiber laser technology apply only one imaging technique (confocal microscopy, multiphoton microscopy, or Anti-Stokes Raman Spectroscopy). Nevertheless, their combination in a single fiber laser system provides faster and robust information about tissues and possible diseases.
Even though these techniques can lead to making excitation laser systems complex, large, and expensive, this research is very promising. The team plans to produce a fiber laser that emits several excitation wavelengths and various laser beam pulse durations. Such a fiber laser technology allows combining several techniques in one compact device.
To be more precise, the fiber laser system helps to test tissue samples directly after surgery or even during it resulting in more precise detection of tumor margins. “Combining three methods allows superimposing several levels of information and thus obtaining a more precise picture of the cells.”
These fiber lasers provide a simpler way to distinguish cancerous cells from healthy ones. Now researchers are developing an ultrashort laser beam pulse source for the new laser system. It should be noted that this source will synchronously pump two optical parametric oscillators.
It is planned that the fiber laser system will emit several laser beam outputs with tunable wavelengths. Herewith, these laser beam pulses are generated in both the femtosecond and picosecond range. The fiber laser technology is considered to be very promising for the three imaging techniques in a multimodal system.
Moreover, it is required to produce a quick electronic system to monitor the fiber laser in the multimodal system. Herewith, the laser system will operate with the microscope’s scanner technology. Such a benefit of a novel fiber laser system as favorable thermal properties removes the need for additional air-cooling.
Advantages of fiber laser technology make the imaging system less expensive, more energy-efficient, and smaller than traditional microscopes with titanium-sapphire laser systems. The potential applications of novel fiber laser systems include the detection of drugs and nanoparticles in tissues and cells or testing of the effectiveness of cosmetic products.

Researchers from the United States, Germany, and Switzerland have presented a comparison of the properties of two types of laser systems applied in urological procedures. The researchers have determined in which cases it is necessary to use each of them and which settings allow for achieving the best result.
Laser systems have been used in surgery for more than half a century, and nowadays they are used in urology, for example, during operations for bladder cancer, benign prostatic hyperplasia, and urothelial carcinoma. Laser systems offer a number of benefits over conventional surgical devices – their application reduces the cases of bleeding and the risk of complications, allowing surgery to be performed minimally invasive (with minimal damage to healthy tissue).
Herewith, laser systems are different from each other. The suitability of laser beams for specific types of operations is determined by their wavelength, duration, and strength of the pulse. They determine the degree of absorption and scattering of radiation, which means the speed and depth of dissection, the degree of damage to neighboring tissues, coagulation (irreversible changes in the structure of the protein), and carbonation. Different types of laser systems are suitable for various tasks, however, in recent years Ho:YAG has become popular, suitable for a wide range of operations, due to the high degree of laser beam absorption and pulsed exposure mode.
Several years ago, specialists jointly developed and studied a new thulium fiber laser. Its laser beam emission is effectively absorbed in the water, which allows for increasing the speed of the operation. At the same time, the pulses of the fiber laser system reach lower peak power, gently dissecting the tissue, rather than tearing it, and they can operate longer, which gives a more uniform distribution of energy and less damage to the tissue.
At the same time, Ho:YAG and fiber lasers have been already tested during the operation in two modes: quasi-continuous (a sequence of short pulses of equal power) and super-pulse. Each laser system was tested with different laser beam power settings and different speeds. In each case, the depth of dissection, the depth of coagulation, and the degree of carbonation were evaluated.
The fiber laser system allows deeper dissection of the tissue in a quasi-continuous mode, while the laser effectively coagulated the tissue. The fiber laser system in a quasi-continuous mode makes it possible to effectively dissect tissue and coagulate bleeding vessels, although the degree of tissue carbonation is higher.
Fiber lasers are one of the biggest and most significant changes in laser surgery in the last 20 years. The capabilities of these devices are actively studied all over the world, and their flexibility allows them to be used in all areas of urology.

The application of laser systems is widespread when it comes to the welding process. Specialists claim that fiber lasers will soon replace traditional welding technologies. Herewith, the diode-pumped fiber laser systems are most popular due to their low-cost, including the ongoing cost of maintenance, spare parts, and environmentally friendly.
To be more precise, continuous-wave laser systems allow for transmitting continuous laser beam lights that are very appreciated in welding. The combination of fiber laser with the right optics makes the size of the laser beam more focused, for example, a 51μm diameter spot that is 10x smaller than those of pulsed laser system.
Fiber laser systems with an oscillating head provide better welds applying mirrors that can handle high power laser beams of 1.5kW. The benefits of lasers with an oscillating head help to achieve high power density that can melt most metal materials and even vaporize them if needed.
Therefore, there are two types of welds: conduction limited and keyhole welding. Additionally, the molten pool interacts with the beam of the fiber laser resulting in inefficient welds when left uncontrolled. The problem appears in deep and narrow keyhole welding, as well as in small welds.
Moreover, plasma formation can also influence the laser beam and leads to scattering effects that degrade welds. The solution to the problem requires the opinions of specialists. It should be noted that such effects as thermal lens focusing or reflection focusing on the molten pool can lead to a temperature increase in the laser system.
Herewith, “when a gas is heated to a high temperature it can be ionized and turn into a plasma, where metal vapor and dust can be aggregated which generates a “plasma ball” scattering the incoming laser beam in multiple directions.” This fact also decreases the quality of the fiber laser system.
Finally, fiber laser technology is considered to be very flexible compared to fixed fiber optics. It allows for controlling weld depth and width independently. It supposes careful attention to such parameters as power, amplitude, frequency, and average speed. Herewith, low heat distortion plays a crucial role in laser systems.

A team of scientists from Australia has developed a microcavity laser system that emits energy-saving and user-safe laser beams with low pump power. Such fiber laser technology is very potential for nanoscale applications, especially in biology and medicine.
The thing is that it is necessary to look deep inside tissue for biosensing and bioimaging research at the intracellular level. This is the reason why nanosized fiber laser systems have several challenges for these biological applications. These fiber lasers allow for directing the luminescent emitters included in individual nanoparticles to interact with one another.
Then electrons are accumulated at particular energy levels, thereby laser systems help to overcome limits of generally low pump laser beam power’s insufficiency in producing nanoparticles able of lasing. To be more precise, these nanoparticles of the new fiber laser system will emit laser beams at pretty low pump powers.
Herewith, the fiber laser technology has been already tested by the researchers and showed a two order of magnitude lower pumping threshold compared to that generally accessible. The operating principle of the laser system is based on the binding surface of the nanoparticle matrix to create a cavity surface with a uniform single layer.
The researchers claim that it is possible to include the NIR microcavity fiber laser in thick tissues and single cells. Thus, the fiber laser system helps to detect environmental indicators such as temperature, pH, and refractive index. It should be noted that these factors play a crucial role because their change demonstrates the health status of the tissues or cells leading to the opportunity of early-stage disease detection.
Finally, fiber laser technology is very potential for biological applications. The researchers could point nanoparticle fiber laser “inside a cell and illuminate an area of interest inside the compartments of a cell.” Additionally, the opportunity to reduce pump power results in low tissue damage as the laser system penetrates the sample.
Moreover, a narrow laser beam allows for more accurate detection. Nevertheless, interference greatly influences fluorescence-based sensing. According to test results, a single nanoparticle can operate like a fiber laser at low power with a sharp laser beam signal.
