High-performance laser systems and molecular vibrations

Lasers are universal tools that nowadays find numerous applications from entertaining our cats to encryption coding communications. Nevertheless, conventional laser systems can be energy-intensive, herein, the majority of them are made employing toxic materials, for instance, arsenic and gallium. Thus, it is necessary to find new materials and technologies to make fiber lasers more sustainable.
A group of researchers from the U.S. has discovered a new phenomenon that leads to the creation of a fiber laser system with over 40% efficiency that is nearly ten times higher than other similar laser systems. To be more precise, new laser “is made from a glass ring on a silicon wafer with only a monolayer coating of siloxane molecules anchored to the surface”.
Compared to previous versions, this laser system offers improved power consumption, and it is made from more sustainable materials. It should be noted that the operating principle of the surface laser system is based on an extension of the Raman effect that allows understanding how the interaction of light with a material can lead to molecular vibrations resulting in laser beam light emission.
Moreover, this type of laser system has one unique characteristic: the emitted wavelength is determined by the material vibrational frequency, but not by its electronic transitions. That is to say, it is easy to adjust the emitted laser beam light by changing the incident light.
The laser systems based on Raman technology have numerous applications such as military communications, microscopy and imaging, medical area for ablation therapy, a minimally invasive procedure to destroy abnormal tissue such as tumors. The main purpose is to produce a fiber laser system where all of the incident laser beam light will be changed into emitted light.
The thing is that in a usual solid-state Raman laser system, the molecules interact with each other resulting in the performance reduction. That is why a new is required to be developed to overcome this challenge. The researchers confirm that if traditional laser systems are regarded as the old energy-inefficient light bulbs, new laser technology will make new laser systems as energy-efficient LED lightbulbs – a brighter result requiring lower energy input.
Finally, the efficiency of motion movement is increasing as well as the ability to act as a laser system by constraining the motion. Therefore, the molecules are set to the surface of an integrated photonic glass ring that limits an initial laser beam light source. Herewith, the laser beam light inside the ring excites the surface-constrained molecules providing the efficiency of nearly 10 times higher, even despite there is less material.

Fiber laser systems for material processing demonstrate their efficiency

Fiber lasers are often used in a combination with direct-diode laser systems. Herewith, a fiber laser contains an optical fiber that is an end- or side-pumped while a direct-diode laser system includes a non-gain optical fiber that is simply filled with light that is produced from numerous laser beam diodes connected to the fiber.
It should be noted that it is possible to apply both fiber lasers and direct diode laser systems for material processing. High-power fiber laser systems include either single-mode or multimode outputs while direct-diode lasers are always multimode because “the etendue of fiber optics for combining light from many laser beam diodes will be substantially above the single-mode limit”.
Nowadays manufacturers of laser systems are constantly improving the brightness of laser products, herein, numerous material processing applications need for the multimode laser beam. Additionally, the majority, but not all, direct-diode laser systems emit laser beams in the near-infrared.
The wavelength-multiplexing of the laser stacks and polarization-combining submodules allows achieving high-power laser beams. Thus, it is possible to achieve a power of 6 mm-mrad over a broad range of power levels from 100 W to beyond 1000 W. 
Moreover, a laser beam can then be transmitted to the workpiece in free space or through optical fibers with a core size of 100 or 200 µm. Finally, the laser technology of wavelength multiplexing enables such laser systems to produce within a wavelength range of 900 to 980 nm.
Material processing application also uses laser modules for the same purposes. To be more precise, basic laser modules can reach a bandwidth of less than 25 nm and output power of 1.5 kW. The application of laser modules includes cutting and welding as well as high-energy laser pumping.
Nevertheless, the laser technology of wavelength multiplexing increases the power levels of this platform far into the multi-kilowatt range without any variation in laser beam properties. Laser modules can include high-power fiber optic cables and laser processing heads resulting in higher power and efficiency.
The laser system demonstrates the ideal application in soldering microelectronic parts, where relatively tiny spot sizes varying from 0.2 to 3 mm are set over a fairly long working distance. Also, the fiber laser system offers such benefit as a quite short rise- and fall-times (less than 10 µs), herewith, it keeps up a uniform power distribution across the laser beam resulting in a perfect solution for multiple heat treatment applications.

Tunable fiber laser generated with laughing gas

A team of researchers from the U.S. has developed a compact laser system that allows creating a tunable fiber laser that can be tuned over a wide range. To be more precise, the fiber laser is made from commercial off-the-shelf elements and is produced to emit terahertz waves by spinning up the energy of molecules in nitrous oxide (laughing gas).
The tunable fiber lasers provide new data information from the novel computational techniques. Such gas laser technology was regarded as the old one for a long time, therefore, researchers thought that these laser systems were big, low-power and nontunable, that is why terahertz sources are considered to be potential.
Modern tunable fiber lasers have a compact size, can be tuned and offer more efficiency parameters. Additionally, it is possible to put such a fiber laser system in one’s backpack or vehicle for wireless communications or high-resolution imaging. The design of the tunable fiber laser is based on the research done in the 1980s, according to which a gas laser system allows emitting terahertz laser beam waves, herewith, the fiber laser is smaller than conventional laser devices, and at pressures far higher than the theoretical models of the time suggested.
Manufacturers of those fiber laser models did not pay attention to several vibrational states, “assuming that only a handful of vibrations were what ultimately mattered in producing a terahertz wave”. According to the previous models, if a cavity is tiny, molecules vibrating in response to an incoming infrared laser system will collide more often and produce their energy rather than building it up further to spin and emit terahertz waves.
The new fiber laser model enables us to track thousands of relevant vibrational and rotational states among millions of groups of molecules within a single cavity. Then the laser technology performs analyzing how those molecules response to incoming infrared laser beam light, depending on their position and direction within the cavity. The researchers succeeded to discover that the inclusion of all these other vibrational states in tunable fiber lasers (previously ignored by people) lead to the appearance of a buffer.
For the new model, a quantum cascade laser system has been chosen as the infrared laser beam source. The opportunity to change the frequency of the input fiber laser by turning a dial may change the frequency of the terahertz coming out. Several gas libraries were looked through by researchers in order to detect those that were known to rotate in a specific way in response to infrared laser beam light, finally deciding on nitrous oxide.
The stimulation of the quantum cascade laser system results in the creation of a tunable fiber laser at a much smaller size than previously considered possible. At present, researchers include other gas molecules, for example, carbon monoxide and ammonia, offering a menu of various terahertz generation options with different frequencies and tuning ranges, paired with a quantum cascade laser system. They plan to achieve more focused laser beams and higher powers.

Fiber laser systems for marking business

The technology of marking on items is regarded as one of the oldest since our ancestors put various markings and engravings on rocks and bones half a million years ago. Nevertheless, nowadays marking technique performed by modern fiber laser systems remains an essential aspect of a business.
It should be noted that the first pneumatic device for marking was designed in the U.S. in 1973. It allowed people to understand the importance and vital application of marking to a business resulting in the fiber laser marking area. First laser systems were used for marking and engraving on metal. They offered low energy transfer efficiency and had huge size, that is why they were soon replaced by the diode-pumped laser technology for marking.
The new laser system offers such benefits as compactness and efficiency over the previous generation leading to the use in numerous scientific applications. Nonetheless, this marking machine was also improved and the fiber laser sourced marking machine has appeared. The fiber laser technology is widely used for marking and personalization in most industries due to their accuracy, higher cost-performance ratio, and extensive application on sophisticated parts.
Additionally, there are laser system machines for marking non-metal products. For instance, CO2 fiber lasers can be used for these purposes. To be more precise, “the marking industry has been advancing with the enterprises and becoming one of the essential parts for companies, especially those in industrial and manufacturing areas”.
Thus, all business sectors can take advantage of marking by fiber laser systems. For example, fiber laser technology provides high quality marking that is considered to be the biggest benefit over other marking techniques. The laser beam has a smaller size than physical engraving, herewith, the laser system is controlled by a computer, therefore, increasing significantly the accuracy. Modern fiber laser systems for marking enable to produce complex forms, making small figures and text more readable.
Moreover, fiber laser marking allows every business to make their product unique to increase sales and promote better brand recall and loyalty. CO2 fiber lasers for non-metal materials help engraving unique text, graphics and barcode to distinguish your products from the others since personalization plays a crucial role for businesses now.
Finally, the ability of fiber laser systems to penetrate and engrave is another great benefit of laser marking because they favor reducing not only time but costs in manufacturing as well. Herewith, the quality and durability are not lost during the process of laser system marking.

Dissipative solitons in fiber laser systems

It should be noted that dissipative solitons are considered to be self-localized coherent structures issuing from the balance between energy supply and dissipation. Breathing dissipative solitons find their applications both in nonlinear science and practical applications, for instance, in spectroscopy. Herewith, the main application is in a mode-locked fiber laser system.
The thing is that these solitons prevail in the laser system cavity under the pump threshold of stationary mode-locking. The fiber laser systems allow performing fast detection resulting in the observation of the breather and breathing soliton molecules’ temporal and spectral evolutions in real-time. Therefore, breathers offer a new mode-locking regime into ultrafast fiber lasers.
The researches of dissipative solitons may promote the design of advanced laser beam sources and discover new opportunities for generating breathers in different dissipative systems. The breathing dissipative solitons in fiber laser systems are regarded as highly attractive in optics due to such features as “their strong connection with the Fermi-Pasta-Ulam paradox, formation of rogue waves, turbulence, and modulation instability phenomena”.
Additionally, dissipative solitons in laser systems play an important role in practical applications, for instance, breathers enable to increase the resolution of microresonator-based dual-comb sources. Herewith, mode-locked fiber lasers propose an ideal platform for the fundamental exploration of complex dissipative nonlinear dynamics.
Also, mode-locked fiber laser systems have allowed different notable nonlinear phenomena (rogue waves, soliton molecules and molecular complexes, pulsations of soliton bunches, and soliton explosions) to be observed. The thing is that several operating regimes are distinguished in which laser beam oscillators may produce breathing solitons with large ratios of maximal to minimal energies in each period of pulsation.
Nevertheless, the observation and characterization of the laser system regimes remain challenging because of the fast evolutionary breather behavior and relatively slow speed of conventional measurement devices. The use of breather fiber lasers is highly promising and may find their applications as direct sources of supercontinuum light, while the periodic variation in output pulse parameters offered by these fiber laser systems can be employed as well.

High powered fiber lasers reduce critical blood incubation time

A team of researchers from Australia has developed a technology based on high powered fiber lasers that is considered to be the first of its kind resulting in the opportunity of pretransfusion testing out of the pathology lab and into point of care. Thus, the new fiber laser technology allows improving pretransfusion testing, such fiber laser reduces blood incubation time from today’s standard of five minutes to 40 seconds.
It should be noted that the process of blood transfusion plays a critical role in numerous hematological conditions such as cancer, bleeding trauma, childbirth, and major surgery. The new fiber laser system enables to prevent fatal blood transfusions for critically ill patients and even in the case of mass trauma. Additionally, high powered fiber lasers are able to determine fetus-killing antibodies in pregnant women.
To be more precise, the fiber laser technology can be especially effective when such factors as time and precision are vital, for instance, in critical and emergency events like mass trauma, where it is necessary to perform pretransfusion testing quickly in order to save lives. Compared to high powered fiber lasers, traditional incubation technique requires more time resulting in remarkable effect at survival chance of a patient.
The operating principle of the developed fiber laser system is based on “the laser incubation model in which a targeted illumination of a blood-antibody sample in a diagnostic gel card is converted into heat by way of photothermal absorption”. Herewith, the high powered fiber laser can heat he 75-μL blood-antibody sample to 37 °C in under 30 seconds.
The near-infrared fiber laser incubation demonstrates that red blood cells act as photothermal agents causing fast antigen-antibody binding with no considerable damage to the cells or antibodies for up to 15 minutes. Therefore, the technology based on high powered fiber lasers performs immunohematological testing faster and more sensitive than current best techniques, herein, clearly positive results are shown from incubations of just 40 seconds.
Moreover, the fiber laser system helps to discover the role of incubation time and temperature of the IgG anti-D antibody and the Rh blood group system’s D antigen. The thing is that the mentioned antibodies are responsible for the hemolytic disease when the mother’s and baby’s blood types are incompatible. Finally, precise testing by high powered fiber lasers for pregnant women’s antibodies is highly important to save the fetus or newborn.

Ultrafast machining by a high-rate fiber laser system

The opportunity to combine high-rate fiber laser systems and high-speed scanning systems allows performing fast and precise machining process of large substrates. Nowadays microprocessing using high-rate laser systems is considered to be a key laser technology for modern microfabrication and production. 
To be more precise, the operation of new high-rate machining technology is based on the benefits presented by high-power fiber lasers and high-speed processing, the main purpose of which is the implementation of advanced and reliable laser system micromachining processes from the lab to the industry resulting in high productivity, processing speed, and throughput. 
This purpose becomes easy to achieve due to “recent progress in the development of fiber laser sources supplying hundreds to thousands of watts of laser system power with excellent laser beam quality, as well as high-average-power ultrafast lasers.” Herewith, the advantages of ultrafast scan systems enable to avoid thermal damage to the substrates, even at high laser beam powers, by redirecting the laser beam of high quality at unprecedented speeds during the process of high-rate machining.
Also, it is possible to use large-aperture polygon-mirror-based scan systems with long-focal-length objectives to provide fast laser beam-spot motions varying between several tens of meters to kilometers per second. For instance, high beam quality laser allows delivering spot sizes of several 10 µm over large scan fields up to 700 × 700 mm2. It is possible to control fiber laser activity by fast laser beam switching to accurately synchronize the laser beam with the ultrafast polygon scanning system.
Thus, the technology of high-rate micromachining by fiber laser system is an ideal solution when it comes to the production of microscale surface features with structural dimensions ranging from hundreds of nanometers to several tens of micrometers. The laser system provides data information that can be applied to control mechanical, chemical, and physical surface features, for example, self-cleaning and wettability, static friction and adhesion, optical and microfluidic properties, etc.
It should be noted that the equipment is required to be installed into a reliable micromachining system to use all the benefits provided by the polygon scanner system and the full power of the laser beam source for industrial applications. The fiber laser system offers high precision and high dynamic processing of large and flat glass and metal substrates. Additionally, the laser system can be specially configured in dynamics, metrology, handling, and laser beam components in order to meet a customer’s targets.

New fiber laser system finds submarines

Recently it was noted that a team of researchers from China has successfully tested a new fiber laser system mounted on a plane flying over the South China Sea earlier this year. The laser system allows achieving 160 meters below the sea surface resulting in a significant boost of China’s naval deterrence capabilities.
Nevertheless, it should be noted that the exact location and the environmental conditions can not be established by the fiber laser during tests. The thing is that the required power applied to produce the laser beam must be large for a laser system to penetrate water efficiently.
According to the South China Morning Post, the fiber laser system emits green and blue light laser beams, which are regarded to be better equipped with the required wavelength to penetrate the surface of the water where it is harder for light to achieve. It also should be noted that the laser system power employed on previous tests is shut down by size limitations of laser modules, however, the latest test of the fiber laser may promote a crucial technological breakthrough.
Modern submarines have a diving depth of 180 meters below sea level, although its real diving depth could be deeper. Therefore, the laser systems with high reach are required. The fiber laser technology is considered to fundamentally change submarine warfare resulting in an opportunity to detect another submarine before it enters the territorial waters of a country.
Nowadays Sonar (sound navigation ranging) is the most popular submarine detection technique but Sonar technology becomes inefficient when a water body gets busier. Then the laser system technology comes to help whether there are airborne, or even satellite-mounted fiber lasers.
Herewith, the research team takes part in the “Guanlan” (Sea Watcher) project, whose purpose to develop a laser system satellite that emits a laser beam that can achieve 500 meters below the sea surface. Since most current submarines can be beyond the maximum depth thresholds and even much deeper, the test of the fiber laser system “simply formed another piece added to China’s “anti-access” military strategy, which is designed to deny anyone from entering its territorial waters”.
The detection systems based on fiber laser technology would enable Chinese military planners to be able to “triangulate and identify other vessels underwater”. Additionally, tests applying similar technology demonstrate the opportunity to penetrate 200 meters below the water’s surface, however, the laser systems still offer less efficiency in busy waters because it is possible to confuse them by sea life, clouds or murky water.

Fiber laser systems stop cruise missiles

Nowadays the fantastic application of laser systems becomes true, and today weapons based on laser technology are used whether in the hands of infantry, mounted on trucks, armored vehicles, warships, and even Air Force fighters. Therefore, it is planned to use fiber laser systems for the destruction of cruise missiles.
To be more precise, fiber lasers emit laser beam light to create intense heat. It means that such laser systems offer practically inexhaustible “ammunition”, herewith, the cost per shot is pretty low compared to a missile or even a cannon shell. Other advantages of fiber laser systems include fast speed and accuracy, although they are considered to lose coherence over distance. 
It should be noted that “the more powerful the fiber laser, the further it can go and the quicker it burns through its target—but the larger its power supply and cooling system have to be.” The U.S. Army confirms that ground-based laser systems will ensure an effective and cost-efficient laser device that allows defended against drones and surface-skimming cruise missiles.
Fiber laser systems demonstrate their particular efficiency as short-range air defense systems against Unmanned Aerial Vehicles because of the common slowness. Thus, the laser system has enough time to burn through the drone’s skin and damage critical bits of the airframe. Moreover, anti-drone application of laser technology has been already tested and was recently employed in combat for the first time when a Turkish laser system applied by a faction in Syria stop an enemy drone.
By 2022, it is planned to create the first four-vehicle platoon of eight-wheel armored vehicles equipped with a turret-mounted 50-kilowatt fiber laser system. Finally, such laser modules will become a common support asset in U.S. brigade combat teams. Nevertheless, laser systems face great challenges from jet-powered cruise missiles, the thing is that even slow missiles tend to scream towards their targets at 500–600 miles per hour resulting in little time left for fiber lasers to stop the missile’s skin target.
Additionally, the fiber laser system has to somehow cause heat damage to an element that will avert the cruise missile from sailing forward on sheer momentum to hit its target because the laser module does not use kinetic force to “push” the missile. Now the development of the 100 KW laser system is regarded as an interim step before the creation of a 250 or 300 KW weapon based on the laser technology resulting in overcoming “more stressing threats”.

Compact fiber laser system operates inside living tissues

A compact fiber laser system that can operate inside living tissues without damaging them has been recently developed by a team of researchers from Northwestern and Columbia Universities. The developed fiber laser has a thickness of just 50 to 150 nanometers that is considered to be about 1/1,000th the thickness of a single human hair. Thus, the advantage of the laser system size allows the laser to fit and operate inside living tissues resulting in efficient detection of disease biomarkers or even potential treatment of deep-brain neurological disorders, such as epilepsy.
Moreover, the researchers confirm that the tiny fiber laser system demonstrates specific promise for imaging process in living tissues. Also, such a laser system is regarded as biocompatible one, it is possible to excite the fiber laser with longer wavelengths of light produced by a laser beam enabling to emit at shorter wavelength.
It should be noted that longer light wavelengths are required for bioimaging process because such laser systems are able to penetrate farther into tissues than visible wavelength photons. Nevertheless, laser beam light with shorter wavelengths is often needed at those same deep areas. That is why the developed fiber laser system is an optically clean system that allows efficient delivering of visible laser beam light at penetration depths accessible to longer wavelengths.
Additionally, the tiny fiber laser can be used in extremely confined spaces, comprising quantum circuits and microprocessors for ultra-fast and low-power electronics. Although the need for increasingly tiny laser system or laser modules does not decline, there is one disadvantage, which the researchers face; tiny fiber lasers offer less effectiveness than their macroscopic counterparts and these laser systems use shorter wavelengths to power them.
The thing is that such disadvantage cause challenges because “the unconventional environments in which people want to apply tiny fiber laser systems are highly susceptible to damage from UV light and the excess heat generated by inefficient operation”. However, the researchers were able to develop a fiber laser platform that solves these problems by applying photon upconversion. To be more precise, “low-energy photons are absorbed and converted into one photon with higher energy” in the fiber laser system during the process of upconversion.
The developed fiber laser was tested, and the researchers succeeded to produce “bio-friendly” infrared photons and upconverted them to visible laser beams. Finally, the laser system can operate under low powers and it is smaller than the light wavelength, it produces visible photons when optically pumped with light human eyes cannot see. Herewith, the compact fiber laser systems can function at powers that are orders of magnitude smaller than observed in any current lasers.
