The process of precise metal cutting by hand is considered to be very challenging that is why the need for safer, quicker, and easier technology increases. Fiber laser technology is perfect for cutting because it focuses on laser beams of light to cut different materials, especially metals that are difficult to process compared to standard ones such as wood, acrylic, and MDF.
To be more precise, numerous types of laser system cutters are distinguished, however, CO2 and fiber laser cutters are regarded as the most popular. The thing is that these systems are very different from one another, herewith, they can be dangerous if applied improperly.
It should be noted that CO2 laser systems use oxygen assistance to cut metal. Safety rules are highly important here because these laser systems can provoke lacerations, burns, and immediate blindness, as well as combustion or explosion (because of oxygen) when employed improperly.
Fiber lasers, in turn, have a higher level of power, therefore, they also have similar consequences when used improperly. It is very important to wear safety equipment? for example, safety glasses and gloves when working with fiber lasers and apply the appropriate laser beam coatings.
Additionally, the application of fiber laser systems requires a well-ventilated room because some laser systems can emit noxious or even toxic fumes. There is an opinion that laser beam cutting is a challenging task since some metals are difficult to cut because of their properties (density, reflectivity, and the way they absorb heat).
Sometimes the cost of CO2 laser systems is cheaper, but they always need oxygen and are limited to cutting less-reflective metals, while fiber lasers do not require any additional components but their cost is typically higher. Thus, the cost of both types limits the metal cutting to professional and industrial applications.
Experts offer several pieces of advice to make the laser beam cutting process easier and faster and get the best results. Herewith, it is necessary to pay careful attention to various materials processed by CO2 or fiber laser systems. The advice is the following:

• Elevate the material by a platform raised on spikes in order to decrease the heat dissipation.
• Conduct tests in order to save a lot of future hassle.
• Separate gas from the laser system if oxygen or nitrogen is used for safety. 
• Make good cuts.

The high-powered fiber laser system demonstrates high efficiency during field testing to make hard rock weaker, improve the cost of geothermal drilling, a laser beam process applied to achieve geothermal heat that is considered to be a clean and stable source of energy.
It should be noted that the drilling process deep into the earth’s crust leads to an increase of a drill bit temperature, herewith, in this case, the drill bit wears faster and its penetration rate reduces. Therefore, the cost of drilling without fiber laser application is extremely high, and this problem bothers investors to be involved with deep geothermal projects.
Nevertheless, a team of researchers from Germany has developed a fiber laser technology for laser beam drilling of hard rock that potentially allows both enhancing the penetration rate of geothermal drilling and saving the cutting edge of the bit by loosening and destroying the rock immediately before the drilling begins.
The operating principle of the system developed is based on the installation of ytterbium fiber laser (with an output power of up to 30 kilowatts) on a test rig. The fiber laser system has been already tested on such materials as sandstone, granite, and quartzite, all of which are regarded as hard rocks with a strength of more than 150 megapascals.
The researchers apply a water-jet to direct the laser beam to the rock face like optical fiber directs the laser beam. Such fiber laser technology secures from contamination and damage to the sensitive laser optics and simplifies the removal of the rock debris by the drilling device. Then the team employs “the laser system on the drilling rig in a specially developed drill string and tests the new tool under realistic conditions in field trials, which also proved to be a success.”
Additionally, the researchers plan to further increase the distribution of the laser beam power and add several sensors to the hybrid device to achieve feedback from the drilling process by the fiber laser system resulting in the opportunity to respond to changes in material along the drilling path.
Also, it is possible to adjust quickly the output power of the fiber laser making it particularly helpful in drilling processes. The thing is that such a drilling system based on fiber laser technology allows decreasing the cost of deep geothermal drilling in the future and expand the application of geothermal energy as an inexhaustible source of energy replacing other renewable sources, for example, sunlight, wind, and water.

The selective sintering based on fiber laser technology is considered to be a process that applies a laser system to heat powder materials leading to the fusion of micron-scale particles to create a solid mass, herewith, this technique finds its popularity in numerous manufacturing processes today. Herewith, previously the laser technology has been limited to printing with one material at a time.
Nevertheless, now the problem has been overcome by changing the whole laser system process to provide printing with multiple materials. To be more precise, scientists moved the fiber laser so that it points upward instead of downward into the heated place leading to no need for a powder bed.
It should be noted that the scientists install several transparent glass plates, herewith, they coated them with a thin layer of various plastic powder. Moreover, they make a print platform lower onto the upper surface of one powder, therefore, directing a laser beam of high quality upward from below the plate and through the bottom. 
Such a fiber laser technology enables numerous materials to either be combined into a single layer or stacked. Thus, a large powder bed is not required anymore because it promotes the sintering of various powders in a single layer. Also, a prototype laser system has been already tested and shows “a 50-layer-thick, 2.18-mm sample out of thermoplastic polyurethane (TPU) powder with an average layer height of 43.6 μm, and a multi-material nylon and TPU print with an average layer height of 71 μm.”
The thing is that the developed fiber laser system for 3D printing offers such qualities as the feasibility of the process and the capability to make stronger, denser materials by pressing the plate hard against the hanging part during the process of sintering by the fiber laser.
Finally, the scientists claim that laser technology is regarded as highly promising and can find potential applications in printing embedded circuits, electromechanical components, and even robot components. Moreover, laser beams enable to produce machine parts with graded alloys, which composition transforms gradually from one end to another.
Thus, the opportunities of laser systems for sintering will be greatly expanded toward a wider variety of industries by allowing the production of complex multi-material parts without assembly. The thing is that the fiber laser technology can change the additive manufacturing industry from printing only passive uniform parts, toward printing active integrated systems.

Numerous quantum laser technologies imply the application of narrow-linewidth tunable diode lasers, amplified and frequency-doubled laser systems, frequency combs, and wavelength meters. Fiber lasers play a crucial role in quantum technologies. For instance, the laser systems are considered to be a product of the first quantum revolution but their use is not limited to just optical quantum technologies. The fiber laser systems are widely utilized in numerous quantum setups.
It should be noted that laser beam light sources create the basis for quantum networks, i.e. “photons are regarded as the natural carriers of quantum states over long distances.” Laser systems are important in the production of such devices as quantum computers, quantum sensors, and optical clocks. To be more precise, fiber laser technology offers total control over all degrees of freedom of the laser beam light, quite often at the quantum limit resulting in an incredible way to start, manipulate and read out various quantum tools.
Additionally, laser systems provide such qualities as wavelength, linewidth, power, polarization, temporal, and spatial laser beam profile. Nevertheless, a single frequency fiber laser system is not always suitable for several applications. For example, two phase-locked laser systems allow operating transitions in atoms that a single fiber laser could not manage. Herewith, the laser beams can be applied as optical traps in order to direct the movement of the atoms. One more application includes cooling atoms as far as to the absolute ground state, required in total control over the spectral qualities.
Moreover, high-powered laser beams are essential when scaling quantum computers where it is necessary to address individually each ion. Fiber laser systems are perfect in operation with optical amplifiers, for example, semiconductor-based tapered amplifiers, and spectral qualities provided by laser technology enable to inherit them. “Therefore, starting from a single laser system that is tailored to offer the required, very specific spectral qualities, laser beam splitting and concatenation of tapered amplifiers provides the necessary scalability.”
It is not surprising that numerous setups need for several fiber laser systems (some a dozen of them), all with various properties taking into account the relevance and versatility of lasers for quantum technologies. Nonetheless, some applications of quantum computers require few laser systems of the same type in one setup, increasing the whole number to tens of lasers.

One popular company-manufacturer of medical devices has presented innovative fiber laser technology that allows decreasing treatment time and increasing procedural efficiency. The super pulsed laser system is based on the thulium fiber laser technology developed for stone lithotripsy and soft tissue applications.
To be more precise, the presented laser system obtained the regulatory approval that enables to apply the fiber laser in the medical world globally. The fiber laser system has been already tested on synthetic kidney stones and demonstrated that this technology can dust stones in half the time it takes other systems, while also creating a fine dust that is easily removed. 
It should be noted that the laser beam application in early cases leads to the system has practically no retropulsion at chosen settings and the fiber laser provides accurate soft tissue cutting with visibly improved hemostasis capability. The super pulsed thulium fiber laser system changes game rules in medicine.
The laser system is considered to be faster, herewith, it dusts stones into tiny particles that more easily wash out during the procedure, which is a crucial advantage for patients. The thing is that “when kidney stone fragments don’t clear during or after the lithotripsy procedure, they can potentially grow into bigger stones that lead to future stone related events such as painful colic and the need for urgent intervention.”
According to specialists, this fiber laser technology is regarded as highly promising and even superior in several features and performance metrics. The operating principle of the fiber laser is based on a laser module configuration unique within the medical area, providing the broadest range of settings available, containing very low energies, and high laser beam frequencies that can transmit superior performance across a range of applications.
Additionally, the laser beam has energy emitted at 1940 nanometers (the optimal wavelength for peak absorption in water), therefore, it is possible to increase energy absorption four times greater than conventional fiber laser systems used as the current standard of care market today. Also, the super pulsed fiber laser provides ergonomic and environmental benefits. 
The thing is that this laser system is very compact compared to similar systems, for example, it fits on a standard wheeled OR cart, as well the fiber laser demonstrates higher efficiency, while it needs just a standard 110-volt power outlet. Herewith, the fiber laser system is significantly quieter than other systems, producing 50% less noise at comparable settings.

The welding technology by fiber lasers continues to grow as a promising technique with developments in weld quality, reliability, and performance. Most fiber laser welding applications are regarded as autogenous, it means the weld is created entirely by melting parts of the base metal and no additional filler wire or powder is applied.
To be more precise, welding applications of a laser beam are almost always autogenous for a huge variety of materials. Nevertheless, there are specific materials and challenging applications of laser systems that need the use of filler material in the welding process resulting in great improvements.
The improved fiber laser system provides better joint fit-up tolerance, avoiding solidification cracking during the welding process, the laser system welding changes the chemical composition or the microstructure of the weld metal to obtain suitable mechanical properties as well as improves the weld profile.
It should be noted that it is possible to use powder or wire filler material during laser beam welding. Most industrials laser system applications are based on wire use. The main reason for its use is regarded as wire low cost because generally, powder feedstock is more expensive than wire for most materials.
Fiber laser welding with filler wire depends on several conditions that define quality, process speed, and cost. For instance, “the wire feed rate is dependent on welding speed, the cross-section area of the gap between the joint face and cross-sectional area of the filler wire.” Therefore, the application of filler wire in a laser system usually leads to 10-20% reduction in welding speed, for a given laser beam power, to compensate for the fiber laser energy that has to be used to melt the wire. 
Laser beam-filler wire interaction also plays a crucial role. The thing is that short length of wire interferes the wire from being melted at the initial part of the bead, therefore, the laser beam directly leads to the material being melted. The long length of wire, in turn, causes the extended wire end to be pressed against the plate surface. 
Moreover, it is necessary to pay careful attention to the focused spot size: it should be close to the filler wire diameter because small spot size of the fiber laser system compared to the wire diameter results in welds with porosity because the filler wire has not melted properly.
Finally, the fiber laser technology has been tested and demonstrated that fiber laser welding applying filler wire provided effective in producing high quality, robust welds with improved fit-up, reduced weld cracking, and better weld profile. Thus, it is possible to use fiber laser systems in a wide range of applications such as aerospace, automotive, and many industrial fabricating applications.

An international team of researchers has presented the world’s most compact fiber laser that can operate in the visible range at room temperature. Such a laser system emit green coherent laser beam light at room temperature, herewith, it is possible to detect the light by the naked eye applying a conventional optical microscope.
To be more precise, the compact fiber laser system is made of halide perovskite as the material. Therefore, this material enables them to produce coherent stimulated laser beam emission and to confine electromagnetic energy. The generation of laser beam radiation at room temperature requires “fabrication of a cubic-shaped, 310-nm nanoparticle from the perovskite and photoexcited it with a femtosecond laser pulse.”
The design of the laser system reduces efficiently the stimulated emission energy leading to a high enough amplification of electromagnetic fields for laser beam generation. The researchers claim that fiber laser generation is regarded as a threshold process: the nanoparticle with a laser beam pulse is excited and then this particle creates laser emission at a specific ‘threshold’ intensity of the external source.
It should be noted that the light that is not adequately reduced causes no laser beam emission. Additionally, it is not required to use external pressure or very low temperature for the nanoparticle to work as a fiber laser system.  Such a system has been already tested and demonstrated effects described at a regular atmospheric pressure and at room temperature.
Thus, fiber laser technology is regarded as highly promising for producing optical chips, sensors, and other devices that employ laser beam light to transfer and process information, containing chips for optical computers. The green portion of the visible spectrum creates obstacles for the development of laser systems leading to challenges for room temperature nanolasers made of conventional semiconductor materials.
The thing is that fiber lasers that operate in the visible range are more compact than red and infrared (IR) sources with the same properties. “The volume of a small laser typically has a cubic dependence on the emission’s wavelength, and as the wavelength of green laser beam light is three times less than that of IR light, the limit of miniaturization is much greater for green fiber laser systems.” Finally, the developed laser system presents higher importance than previous devices.

Modern laser systems in microscopy allow researchers to discover how molecules within a cell react and interact when it comes to investigating how tumors grow. Such laser beam microscopy requires to be labeled with fluorescent substances that make them visible to researchers, however, this action can misrepresent the molecule behavior. New microscopes based on fiber laser technology operates without the necessity to label the molecules.
A team of researchers from Germany and China has designed the microscope that includes a unique compact fiber laser instead of the solid-state laser systems that had previously been applied. To be more precise, the microscope based on fiber laser technology produces less noise than conventional designs, allowing them to be used in operating rooms. The fiber laser system provides label-free microscopic imaging that is considered to be a popular topic in current biomedical research.
It should be noted that usually staining with fluorescent markers can not be performed at in-vivo tissues, herewith, label-free microscopy plays a crucial role in understanding how different new types of cells develop from stem cells as well as in differentiation a tumor from normal tissue without staining. Fiber lasers allow researchers to operate without markers in the muscle tissue cells of the heart and liver, as well as other cells.
Advanced fiber laser systems find their wide application in optical nanomicroscopes, in which laser beam light is transmitted through glass fibers rather than through a solid body of crystal or glass. Nevertheless, previously solid-state laser systems surpassed fiber lasers because of their higher power and less noise. Researchers used two synchronized optical resonators (laser beam cavities), wavelengths of which were required to hit the specimen through the lens at exactly the same time resulting in challenging control of the whole process.
The developed fiber laser microscope presents an essential benefit that includes easier operation than a conventional solid-state laser system. Additionally, such a fiber laser system is less subjected to error, the process becomes faster because it does not need to label the molecules. Herewith, the prototype of the fiber laser microscope promotes the development of portable devices that can be applied in the operating room, for example, to mark tumor borders during an operation.
The new fiber laser technology provides benefits for numerous biomedical applications, and the early detection of tumors is only one specific example of this. Moreover, it is planned to employ the new fiber laser microscope in clinical applications in the nearest future, because preliminary studies have been already conducted and demonstrated amazing results.

The thing is that the generation of ultrashort laser beam pulses needs careful monitoring of the light’s dispersion provided by a fiber laser. To be more precise, there is a dependency of phase velocity and frequency, so a real laser beam pulse includes a spread in frequency, it will enlarge as it goes through an optical medium. Thus, simple, low-cost sources of sub-picosecond laser beam pulses, soliton fiber laser systems, including a laser diode and an optical fiber, are considered to become an ideal solution.
It should be noted that such laser systems allow decreasing the spread by “balancing it against Kerr focusing—the narrowing of a laser beam pulse caused when light’s electric field alters the medium’s refractive index—so each pulse travels as a soliton, and its duration remains unchanged.” Soliton fiber lasers are regarded as very promising because of such benefits as simple construction, however, they are not able to reach the high energies of techniques, for instance, chirped-pulse amplification.
Nonetheless, new fiber laser technology allows overcoming these limitations. The operating principle of the fiber laser is based on the application of a spatial light modulator to manage the light’s dispersion relation to enabling higher laser beam energy pulses. It should be noted that a dispersion relation demonstrates how a wave’s frequency is relevant to its wavelength. “For light in a conventional soliton laser, the function is approximately quadratic, and its second derivative describes how a laser beam pulse would spread in the absence of Kerr focusing.”
Researchers from Australia have demonstrated that higher-order dispersion provides real benefits. Therefore, a photonic crystal waveguide based on fiber laser technology has been developed where the effects of second- and third-order dispersion were suppressed due to the waveguide’s geometry. Herewith, the balancing process of fourth-order dispersion with Kerr focusing is connected to soliton formation.
The soliton fiber laser system acts by applying the same principle. Nonetheless, the researchers employed a programmable spatial light modulator instead of a specially designed waveguide to produce the required dispersion profile. Additionally, the researchers claim that the energy of the quartic laser beam pulses is regarded as proportional to τ−3, as predicted for fourth-order dispersion solitons.

Laser technology for material processing, which was appeared about three decades ago, is currently experiencing the peak of its development and popularity. Modern fiber laser technologies are rapidly being introduced into industrial production and advertising business, often replacing traditional methods of material processing.
The focused laser beam of adjustable power turned out to be an ideal “working tool” for the creators of new equipment. The laser system for cutting and marking, welding and surfacing, as a material processing tool, works quickly and does not wear out, it is economical, highly accurate, and its impact is easy to control and manage.
Laser  technologies for material processing have a number of advantages that contribute to the expansion of their application in various industries and services:

• wide range of processed materials,
• no mechanical impact on the product with minimal thermal,
• precision and guaranteed repeatability,
• high contrast and durability of the images applied,
• high speed and performance, saving on consumables and low power consumption,
• possibility of laser beam processing in hard-to-reach places, on flat and curved surfaces,
• the ability to integrate the fiber laser into various technological processes, including production lines and robotic systems.

For instance, laser system engraving is effective for personalization of souvenirs and gifts, fiber laser application of personal and greeting inscriptions. Laser beam cutting as a high-precision tool allows producing products with minimal material consumption and without additional processing of the cutting edges. Laser system welding is characterized by high welding speeds and high quality of welds with minimal weld sizes.
Laser hardening
A fiber laser or thermal hardening of metals and alloys by laser beam emission is based on local heating of a surface area under the influence of radiation and subsequent cooling of this surface area at a supercritical rate as a result of heat transfer to the inner layers of the metal.
In contrast to the known processes of thermal hardening by quenching with high-frequency currents, electric heating, melt quenching and other methods, heating during laser beam hardening is not volumetric, but a surface process. At the same time, the heating time and cooling time are insignificant, there is almost no exposure at the heating temperature. 
These conditions provide high rates of heating and cooling of the treated surface areas. Due to these features, the formation of the structure during laser beam heat treatment has its own specific features. The main purpose of fiber laser thermal hardening of steels, cast iron, and non-ferrous alloys is to increase the wear resistance of parts working under friction conditions. 
As a result of laser system hardening, high surface hardness, high dispersion of the structure, a decrease in the coefficient of friction, an increase in the bearing capacity of the surface layers, and other parameters are achieved. Fiber laser hardening provides the lowest wear and friction coefficient, and furnace quenching – the highest. 
Along with this, hardening by the fiber laser system is characterized by very small running time (only two or three cycles), a decrease in the upper values of the number of acoustic emission pulses, and a small interval of change in the number of laser beam pulses. This is due to an increase in the uniformity of the microstructure of the surface area after laser system hardening.
The wear resistance of cast iron and aluminum alloys under sliding friction conditions after continuous laser treatment is noticeably increased. The increased wear resistance of cast iron after laser beam treatment is due not only to the corresponding structural and phase composition but also to improved friction conditions thanks to graphite preserved in the laser zone. It also increases the wear resistance of steels and some other alloys when friction occurs in alkaline and acidic environments.
Laser system cutting
Fiber laser cutting is a laser technology that uses the energy of a laser beam to cut various materials. Laser cutting is usually used on industrial production lines. Technologically, this process is reduced to focusing a high-energy laser stream on the material being cut. The material, in turn, begins to melt, burn, evaporate, or be removed by a stream of auxiliary gas. 
The laser beam cut is characterized by high edge quality and positioning accuracy. Powerful industrial fiber lasers can cut metal sheets and other materials of various shapes with equal ease. Laser system cutting has a number of advantages over other metal-cutting methods. 
Advanced equipment of fiber laser system cutting machine is able to process almost all metals and their alloys. It becomes possible to achieve a minimum area of the cut, while there is almost no deformation of the edges. The purchase of laser system cutting equipment is advisable in cases where it is necessary to perform the following types of work:

• Machine processing of metal without high initial costs and physical contact with metal
• Metal processing without using a large amount of manual labor
• Metal cutting that does not involve further processing of the part
• High-speed metal cutting, which is accompanied by a slight thermal effect on the metal surface
• Cutting of finished products (past painting processes, etc.) without losing the external qualities of the part.

The fiber laser is able to operate in pulse-periodic and continuous modes. The technological capabilities of the laser beam equipment allow performing metal cutting operations that are accompanied by a small amount of waste. Since the laser system cutting machine is characterized by high positioning accuracy, it is possible to significantly reduce the cut tolerance, which leads to the high economic efficiency of cutting. 
The laser beam of high quality makes it possible not only to cut metal with high precision but also to create holes in it with a diameter of 0.2 mm or more. The fiber laser system for cutting is characterized by a high speed of operation, which depends on the power of the laser beam.
Laser cutting equipment makes it possible to process non-rigid parts and parts that are easily subject to deformation. The use of laser technology enables cutting out details of any, even the most complex contour.
Laser engraving
Fiber laser engraving includes the removal of the surface layer of a material (metal, plastic, leather) or coating (paint, electroplating, spraying) under the influence of the laser beam of high quality. Laser system engraving will not be erased and will not fade. It can rightfully be called eternal. 
The laser beam process is controlled by a computer, which allows engraving images from any digital format (after the necessary processing). The laser beam of high quality allows applying high-resolution images. This makes it possible to engrave high-quality microimages and micro texts.
The laser beam modes embedded in the system can vary very widely. This allows adjusting the depth of the burning of the material. For example, there is a deep engraving in metal for maximum clarity and durability or evaporation of the top layer of paint for the product label without affecting the material itself.
In addition to the standard three-dimensional laser system engraving, there is a technology for obtaining color engraving. Colors in fiber laser engraving of metal are achieved due to the appearance of oxide films in the area of laser beam exposure. The laser technology for obtaining them is innovative and unique. The colors are selected separately for each new material.
Laser welding
Fiber laser welding is a welding technology used to attach various parts of metal using a laser system. Due to the high concentration of laser beam energy in the welding process, a small volume of molten metal, the small size of the heating spot, high rates of heating and cooling of the weld metal and the near-weld zone are provided.
The process is often used to perform large volumes of production, such as in the automotive industry. Depending on the purpose, continuous or pulsed fiber laser operation can be used. A laser beam with a pulse time of the order of milliseconds is used for welding very thin workpieces. A continuous laser system is used for deep welding.
Fiber laser welding is a universal welding method that can be used to weld carbon steel, stainless steel, aluminum, and titanium. A high cooling rate can lead to thermal damage when welding carbon steels. The welding quality is high, similar to electron beam welding. The welding speed is proportional to the applied power, and also depends on the type and thickness of the workpieces. 
The high power potential of fiber laser systems makes them particularly suitable for large production volumes. This type of welding is particularly dominant in the automated industry. Some of the advantages of fiber laser welding compared to conventional include: air route can be used to transmit laser beam, that is, there is no need to vacuum, it is easy to synchronize manipulators, there is no x-ray radiation, it provides the best quality of welds.
One of the methods of laser system welding is hybrid laser beam welding. This is a combination of laser and arc welding (gas metal arc welding). The electric arc melts the wire, ensuring a constant arc length, while the wire is put automatically by the wire feeder. Protective gases (argon, helium, carbon dioxide, and their mixtures) are used to protect against the atmosphere, which is appeared from the welding head together with the electrode wire.
