According to scientists, stimulated Raman scattering is still one of the development challenges for multi kilowatt fiber lasers. To make an evolution in fiber laser technology towards multi kilowatt systems with the high-quality laser beam, fiber laser manufacturers should adopt stimulated Raman scattering mitigation strategies. 
Stimulated Raman scattering is a nonlinear phenomenon. It appears when the optical intensity becomes more than the threshold value. Because most of the added energy provided to the fiber laser is wasted, the stimulated Raman scattering restraints the output power.
The optical feedback that reflects from the workpiece could be a reason for serious challenges like fiber laser instabilities or defects to a fiber laser’s pump diodes. The instability of the output power or laser beam can greatly influence the different industrial processes and change the quality of the product. When the effectiveness and the reliability of fiber lasers still are the main qualities for industrial applications.
Despite the enormous progress in Stimulated Raman scattering, the output power of single mode lasers hardly exceeds a few kilowatts. Transverse mode instability is another technical challenge that has a bad influence on the multi kilowatt system development. It is a nonlinear effect that appears in fiber lasers. Transverse mode instability occurs suddenly when the average power limit is reached.
The transverse mode instability is well-known for a long time so scientists could better study it and develop the most effective suppression schemes. The difficulty is that transverse mode instability suppression options often penalize Stimulated Raman scattering suppression. That is why it is necessary to find the right balance, while also paying attention to other standards like reliability considerations and technological limitations.
So the fiber lasers‘ power transcends the Stimulated Raman scattering threshold with the help of the applied traditional approaches. There is no comprehensive solution that is why the constant development helps in fiber lasers‘ understanding at multi kilowatt regimes. Still, there are some issues to be solved to produce reliable and highly efficient industrial fiber lasers.

Ring microlasers have potential light sources for photonic applications. However, there can be some aspects to be solved. For example, connecting several fiber lasers into a set there can lead to unwanted extra modes. However, thanks to modern fiber laser technology, scientists could create chip-sized single mode lasers. 
To develop such a single mode laser with a size of a chip, scientists should make the fiber lasers stronger, smaller, and more stable. Nowadays, a research team from the USA designed two-dimensional arrays of microlasers with the stability of a single mode laser. Moreover, they could achieve higher power density than it was before. 
The developed fiber lasers should be coherent and stable to reserve the data processed by a photonic device. The single mode lasers are the best way for it but their combination is dimmer and less powerful compared to the multimode lasers. Logically, to create high-power multimode laser scientists need to combine several single mode lasers together. But the problem is the competition between modes that makes the fiber laser array less coherent.
It is important to arrange a single mode operation laser because the brightness of the fiber laser array increases with the number of fiber lasers when they are synchronized in one supermode. Researchers made a conclusion that they can reach this single mode operation by including a ‘superpartner ‘ from the concept of supersymmetry. 
According to the research team, the previous works based on the superpartner fiber laser arrays principle were just one-dimensional. The modern fiber laser system shows an array with five rows and five columns of microlasers. Scientists also predict more power scaling using the same formula for a larger array. 
This scientific work could also be applied to the previous research on vortex lasers that can take control of a laser beam and its spiral movement. The capacity to get laser beams under control could give an opportunity for scientists to code fiber laser systems at even higher densities. 
Single mode lasers have a vast range of applications starting from optical sensing and ending with optical communications. And this scientific research could help to make a step forward by developing a more efficient laser module.

We all perfectly know the impact of fiber laser technology on different spheres of science. The accuracy of the laser beam has become irreplaceable to the spheres of medicine, telecommunications, etc. However, just a few people have heard about the fiber lasers‘ appliances as art instruments. And we are not talking about restoring the old artwork like in cleaning techniques. 
As we already know, fiber lasers can cut patterns in materials like paper, wood, and metal. The patterns are highly immune to harsh environments and chemical influence. The scientists used all these features to create a new fiber laser system, that can be useful for some artists and designers.
Recently, the research team from Russia has created a fiber laser paintbrush. It helps the designers who develop, erase or change the colors of strokes on a titanium canvas. 
From the very beginning, the scientists created a device based on fiber laser that produced oxidation to develop a full-color palette on stainless steel. There is no need for any external colorants. In reality, an oxide layer is formed on the top of the metal surface. It has a special thickness and chemical composition. Once the researchers found the certain parameters for each color, they got an idea to invent a special instrument based on fiber laser for it. 
For erasing and rewriting the research team invented a printer that can create titanium artwork based on a fiber laser by using an image. The printer includes a nanosecond ytterbium fiber laser system with a scanner that could move the laser beam. To make the strokes, the fiber laser paintbrush heats the titanium surface. And when the metal cools, a thin oxide layer forms, producing colors. The researchers found out that the color brightness is getting reduced after the second fiber laser pass. They also could change the intensity and scanning speed a little that helped to remove the color completely from the surface.  
The research team created several famous art masterpieces to demonstrate the work of fiber laser paintbrushes. It took just three minutes to create a picture with the fiber laser system that the artists could create for years. Then the scientists are going to develop a fiber laser system as a handheld tool. So the artists could use it more like a real pen or paintbrush.

According to the researchers, battery manufacturing has become a market that demonstrates significant growth nowadays. Mostly, that is because of the accelerated demand from the electric vehicle (EV) industry. Fiber laser manufacturers predict the high growth for integrating fiber laser technology in battery welding equipment (particularly laser-based).
Fiber laser working principles are applied in battery welding. It is not a new laser application but it became really popular only when the electric vehicle (EV) industry started using it. 
Nowadays, researchers are working on creating effective production centers for battery cells for the electric vehicle (EV) industry. They need to investigate how fiber laser technology can be produced to economically contact and join dissimilar materials. So that will help to manufacture battery cells more efficiently and reliably.
There are several scientific projects that are studying the usage of fiber laser technology in battery manufacturing. One of the studies has a goal to find the most effective way to manufacture lithium-ion batteries. The researchers developed a fiber laser system that could join anodes and cathodes to the contacts. The anodes are made of copper and the cathodes of aluminum. The scientists chose different types of fiber lasers for testing. The solution was in applying a turntable with several stations so that a stack is ready in two seconds. 
The other project studies how to connect battery cells more efficiently. The scientists develop processes for bonding copper, aluminum, and steel with a fiber laser working in the nanosecond range. These processes are complicated because thin electrical contacts should not be heated too much. They are sensitive to temperature. It is important to strike a balance here. The connection will not have mechanical stability if there is little welding energy. And on the contrary, when there is too much welding energy, the mode of operation or service life of the batteries can be shorter. 
The third project connected to fiber laser technology includes the experiments on copper-aluminum and copper-steel joints on the pouch and cylindrical cells respectively. The tests demonstrated that they can achieve as good joints as continuous-wave (CW) welding. However,  the energy consumption is much lower. And there is high repeatability and fewer intermetallic phases. The only disadvantage is that the whole process takes more time, so there are still aspects that need to be improved.
In conclusion, the range of laser applications is wide, one of them is battery manufacturing.  The fiber laser systems can unite both a CW fiber laser and a nanosecond pulsed fiber laser. The laser beam can be controlled apart. And except joining, the fiber laser system can also remove material, for example, to construct surfaces.

Thanks to the development of ultrafast fiber laser systems in the last century, nowadays, we can observe a lot of their new applications. Fiber laser technology is applied in medical and industrial spheres starting with a cancer diagnosis and ending with 3D nano printing. So new representatives of compact fiber laser modules make our everyday life easier. 
The ultrafast fiber laser development has led to huge technical innovation in fiber laser technology. The scientists achieved big progress at the quality, lifetime, and price of many types of fiber lasers‘ components including beam combiners, Bragg fiber filters, modulators, detectors, etc. Today, fiber laser modules have the commercial availability of doped fibers for multimode laser pumping to deliver single-mode output for a higher power. This technology is used in high-power fiber laser designs for industrial manufacturing applications.
Nowadays, ultrafast fiber lasers look like small black boxes. So the fiber laser manufacturers can easily incorporate them into a wide range of devices. Fiber lasers‘ effectiveness, their mechanical characteristics like the small size and rugged architecture make them suitable for industrial and medical platforms based on fiber laser technology. Moreover, they demonstrate high stability and reliability.
Fiber laser designs have the potential of high gain and they are compact. Ultrafast fiber lasers even with low power can be used as the building block for higher-power fiber laser designs. These low-power fiber lasers can provide output at a variety of wavelengths. 
One of the latest fiber laser designs was produced in Germany. It is modern two-photon microscopy that is on the base of near-IR femtosecond laser pulses. It allows making high-resolution imaging of human skin called multiphoton tomography. From the very beginning, the scientists used lasers that required water cooling and a complex delivery arm. Moreover, they were expensive and quite huge that created inconveniences. The usage of ultrafast fiber lasers made the operation easier. The fiber laser system requires no water cooling and can be freely moved around a dermatology suite.
However, the small diameter of the fiber core gives some challenges for the scientists who create ultrafast optical pulses. To make an ultrafast fiber laser source, the pulse energies should be low and the chromatic dispersion and nonlinear effects should have a balance. Besides, it is necessary to have a reliable starting mechanism to provide consistent performance.

Different wavelength ranges, short pulse durations, nonreactivity to environmental conditions, small size, and other important factors of fiber laser designs play a crucial role in their popularity among the scientific and government communities. Fiber laser technology often solves problems that other modern technologies can not. Nowadays, we can find industrial fiber lasers in manufacturing, automotive, aerospace, transport, consumer devices, and other industries. 
From the very beginning, when the fiber lasers were implemented they were in great request for the processing of metals. Now they are applied for 3D printing, surface cleaning and modification, and many microprocessing methods of a great variety of materials.
Fiber laser modules can provide higher output powers and laser beams of good quality. That helps to achieve efficient energy consumption and resistance to vibration and environmental conditions. That’s why there is no wonder, they make a fast return on investment. 
The first fiber lasers were mostly effectless. But then new methods of delivering the pump light into the cladding were discovered. These methods allowed making fiber lasers more powerful and showing their true potential. That was a revolution in fiber laser systems and the new era began. As a result of this revolution, fiber laser modules were adapted to mass production.

The researchers from the UK produced a self-cooling fiber laser. This fiber laser is based on a silica fiber laser design. The scientists are going to create fiber laser-based devices that could achieve exceptional purity and frequency stability. That will allow avoiding the necessity of external cooling, for example, using a water-based cooling system.
A self-cooling fiber laser with a silica fiber laser module can be applied for the development of progressive fiber laser systems. These fiber laser systems are useful for low-power, high-precision metrology and information transportation.
The cooling was successfully achieved when the researchers decreased the energy level of the light. The tests’ results demonstrate that the silica fiber laser module getting colder upon light excitation. The scientists also used anti-Stokes fluorescence to achieve cooling. This means an addition of a rare-earth ion to the fiber laser module. The ion absorbs the light from the laser beam and then produces it at a higher energy level. As a result, the fiber laser module temperature is getting lower. 
The process is a complicated task because of the ytterbium that is usually taken during the test. Ytterbium ions can take impurity and release heat energy. This process is called “concentration quenching”. The researchers created a glass composition with the necessary for the experiment quantity of ytterbium to avoid this effect. 
The light frequency and its power were more stable because there were no changes in the temperature of a self-cooling of fiber laser design. That helped to preserve the cooling effect. 
The tests prove that the fiber laser system is capable of supporting high-power and large-scale laser applications in the terms of increasing performance efficiency. There were also developed two additional silica fiber laser applications. The scientists intensified the laser beam at the same time preserving the negative average temperature change. 
According to the researchers who developed these constructions, there is still a lot to improve in the future. The extracting percentage, as well as the level of efficiency, are at a low level. That’s why this newly developed technology can’t be implemented and needs some time for adoption for high-power laser applications.

Specialists have developed new measurement solutions for highly effective manufacturing processes. Their whole design is based on the range of fiber lasers for sensing. The latest fiber laser design of a measuring mechanism allows gaging the inner geometric parameters of the cylindrical steel bands. That function is commonly used in the tire industry for non-contact measurement of steel band rims. This construction can be easily installed on the conveyor for more effective work.

The other function of this machine is that it can be used for creating 3D modeling with the help of fiber laser systems. The mechanism consists of a two-axis motion system that rotates fiber lasers for sensing. That creates a radial 3D scanning frame inside the steel belt. The laser beam allows getting the data about the measured parameters like height, diameter, roundness, chamber width, angle, etc.

The mechanical hardware contains the mounting frame, housing with interfacing connectors, and fieldbus. Fiber lasers for sensing connect a fiber laser module with the probe software and as well with the PLC. The probe software and the fiber laser module are unified to provide all necessary data. The data can be used to display the graphical information about a measured component. Moreover, it provides a file output that can be used in further analysis. The system is suitable for both vertical or horizontal orientation as the customer needs.

The finally developed construction also includes other options with other fiber laser systems. They are used as sub-systems for multiple measurements of different customers’ units, usually as part of manufacturing processes. The different specimens with fiber laser systems constitute fully machine integrated systems, for instance, for welding lines and automated assembly measuring length, diameter, thickness, etc. The rest systems allow manual operation with hand controls or mouse activation to record the results of measurement and display them in real size or as a model.

Scientists from Hong Kong have developed a new hybrid imaging technique that is called optical-resolution photoacoustic microscopy (OR-PAM). The system is based on a fiber laser with a highly concentrated laser beam. It consists of five wavelengths which makes it highly effective in studies and it can be employed in several fields.
The OR-PAM can be applied mostly for multi-contrast functional imaging. During the development, the research team faced some restrictions like the limited laser beam wavelength of most fiber lasers and the limitations of the scanning methods. To get better results the scientists created a multimode laser based on a single fiber wavelength nanosecond laser module source. It takes sub-micro seconds to switch different wavelengths that make multifunctional OR-PAM simultaneous.
The whole fiber laser system is created based on the stimulated Raman scattering (SRS) effect. A fiber laser applies a laser beam with a longer wavelength than the usual one. The generated SRS wavelength remains at high rates when the energy of the laser beam source goes beyond the threshold. Photoacoustic imaging uses the fact that when a surface or tissue is pointed by a laser beam, it takes the light and produces heat. The heat causes thermal expansion, which generates a photoacoustic (PA) wave or a mechanical ultrasonic wave. After that, the scientists can get an image that demonstrates the light absorption distribution.
This invention based on fiber laser technology can be an enormous boon for medicine because it can make a multiparameter image for accounting physiological parameters in vessels like the diameter, depth, etc. That would help to make a disease model while research or treatment. With the help of this five-wavelength OR-PAM, the scientists could also get imaging of tumor development, lymphatic clearance, and brain imaging.
This new system based on the fiber laser can also show the subcellular measures like hemoglobin concentration, blood flow speed, blood oxygen saturation, and lymphatic concentration. That allows the scientists to study disease models, for instance, cancer, and find new ways of treatments for it.
The research team met two main problems while developing multifunctional OR-PAM. The first problem is that the microenvironment of blood vessels changes with time, so long-term scanning with a multimode laser can cause some inaccuracy. The other is the asynchrony among the different laser sources which may cause systematic errors in calculation.
That’s why they created a multimode laser that contains five fiber lasers. This new system can produce multifunctional imaging with a single multimode laser and in a single scanning. So it shortens the time for making an image and improves its accuracy.
