Fiber laser of super-pulsed type offers several benefits

Fiber Lasers and their benefits Researchers from the USA apply super pulsed fiber laser to treat stones, herewith, they also discovered several benefits compared with holmium laser system lithotripsy. Nevertheless, further research comparing the two is still required. The super pulsed fiber laser system is considered to be a new lithotripsy platform that differs from the holmium one used for the treatment of kidney stones.

To be more precise, compared to the holmium laser system that used 200-μm to 365-μm optical fibers, the super pulsed fiber laser enables the application of 150-μm core-sized optical fibers. The researchers demonstrate “a comparison of lithotripsy with 242-μm core-sized optical fiber holmium: YAG (AccuMax 200), to the 150-μm core-sized SPTF.”

The thulium fiber laser platform provides a benefit compared to the holmium: it has a compact size and can be plugged into a 120-volt outlet as a standard mobile phone. Another benefit of fiber laser technology includes the absence of noise. Herewith, the super pulsed laser system provides settings that the holmium does not, containing high-frequency settings up to 2400 Hz. Therefore, the fiber laser system allows dusting or fragmenting kidney stones.

The fiber laser technology provides high efficiency in stone treatment due to the high absorption of the laser beam energy by water. “The laser beam energy is emitted at a wavelength of 1,940 nm, which is at the tip of the curve for water absorption. For that reason, it is probably more effective than the holmium laser system.” Also, the small profile of the laser beam generated by the super pulsed fiber laser makes it possible to use smaller optical fibers—as low as 50 μm, based on bench testing while holmium laser systems use fibers greater than 200 μm. 

Consequently, the application of smaller optical fibers ensures three other benefits. The first is smaller fibers provide a better flexion to direct the system inside the kidney easier. Additionally, smaller optical fibers have better irrigation during the procedure with a better visualization. The third benefit includes the delivery of laser beam energy in a smaller area of the stone, producing fragments that are smaller dust-type fragments. Thus, virtually all patients with kidney stones who can be treated with the fiber laser system would benefit from fiber laser technology.

Finally, the super pulsed fiber laser is planned to be applied for a retrograde technique in patients that have larger stones that cannot be exposed to the percutaneous approach for reasons such as other comorbidities because it has the potential to be faster in terms of breaking up the stones.

The operation of fiber lasers

A fiber laser is a powerful device for the production of single-mode radiation with the highest possible performance and quality characteristics. Fiber optic systems for processing materials occupy about one-fourth of the entire laser market. 

It should be noted that the diameter of the fiber laser system has micro values, so the laser beam allows for cutting out sharp corners and other complex shapes with absolute accuracy, even in a sheet of metal with high hardness and large thickness.

The beam formed by a fiber laser is designed primarily for working with metal surfaces, so the fields of application include automobile, ship and rocket engineering, manufacturing of sea containers and railway cars, machine tool construction, robotics, marking and engraving, and the military-industrial complex.

In addition to metals, the fiber laser is perfect in working with stone, glass, and some types of plastic, so it is also used in those industries that massively use these materials (for example, the advertising industry, some types of construction work, etc.).

The priority in using solid-state equipment (fiber lasers belong to this category) over any other systems is explained by a large number of economic and qualitative advantages, which are the following:

  • positioning accuracy at all speed modes;
  • high power;
  • excellent laser beam quality with minimal transmission loss and small angular divergence;
  • multi-function: laser systems can not only cut, engrave and perforate materials, but also solder or perform welding, and cleaning of surfaces from any type of contamination;
  • compact size, easy transportation;
  • silent operation and almost complete absence of industrial waste.

The fiber laser system consists of two main parts: pump lamps (semiconductor diodes) and fiber optic cable. A light-conducting optical fiber with a core of transparent quartz doped with rare earth elements is inside the cable (this is ytterbium in most machines used in industry). 

At the ends of the central rod, a fiber Bragg grating (FBG) is most often performed. The notched sections have a modified reflectivity and act as resonators, reflecting light propagating along the optical fiber and maintaining the desired wavelength. The laser beam retains its monochrome and other quality characteristics thanks to them.

The new vertical-cavity surface-emitting laser system

A team of scientists from the U.S. has demonstrated a new design of a vertical-cavity surface-emitting laser system that provides record-fast temporal bandwidth. The developed fiber laser technology is based on the combination of numerous transverse coupled cavities that increases the optical feedback of the fiber laser.

It should be noted that the new laser system plays a crucial role in the production of energy-efficient and high-speed optical interconnects in data centers and supercomputers. To be more precise, vertical-cavity systems are a class of semiconductor laser beam diodes combined with a monolithic resonator that produces laser beam light in a direction perpendicular to the chip surface.

Herewith, this type of fiber laser systems becomes more popular thanks to its advantages such as compact size and high optoelectronic performance. For instance, compact laser systems can be applied as “an optical source in highspeed, short-wavelength communications, and optical data networks.”

Additionally, small fiber lasers find applications in automotive or data communications to detect dense traffic and high-speed transmission. Nevertheless, the current fiber laser system has its speed limitation such as the 3-dB bandwidth. Moreover, such parameters as thermal effects, parasitic resistance, capacitance, and nonlinear gain effects also influence the laser.

The thing is that the direct modulation of this fiber laser system cannot be higher than 30 GHz because of the nonlinear optical amplification phenomenon. Nonetheless, the new fiber laser technology has a revolutionary novel design for lasers. The used multi-feedback technique that unites numerous coupled cavities allows for carefully direct and control of the laser beam. Therefore, the researchers can increase the strength of the feedback and expand the temporal laser beam speed leading to overcoming the current limitations.

The fiber laser technology is novel. Now the direct feedback from each cavity is required to be moderate and then the researchers can direct them accurately via the coupled cavities resulting in more design freedom of laser systems. They also claim that new modulation bandwidth can achieve the 100 GHz range.

Thus, the design of fiber lasers has greatly changed. The novel coupled cavities enable to carefully monitor the feedback to the laser system reached by greatly slowing the laser beam light down. Moreover, now it is possible to produce lasers of various designs for particular applications in both fundamental science and technology due to this technique. The new applications of this fiber laser system include the automotive industry where the laser beam acts as a proximity sensor or the smartphone’s face ID, as well as the use for quantum information processors such as coherent Ising machines.

Fiber lasers produce perfect laser beams

A team of researchers from Germany has presented an ultrafast fiber laser system. It allows for producing an average power that is higher than 10× that of standard high-powered lasers. The fiber laser technology enables researchers to change both the speed and efficiency of industrial-scale materials processing.

It should be noted that the developed fiber laser has been already demonstrated at the OSA laser congress. The thing is that there is a combination of 12 laser beam amplifiers in the new laser system. Herewith, these lasers overcome current limitations provoked by laser beam light emission and waste heat.

Additionally, optical fibers used in fiber laser systems show “a laser beam geometry with a high surface-to-volume ratio. They effectively dissipate this heat. Therefore, current high-powered laser systems obtain an average power of 1 kW.” Nevertheless, the power increase leads to a decrease in laser beam quality because of the generated heat load, creating a limit.

Thus, the application of 12 amplifiers makes it possible to develop a laser system that can generate 10.4 kW average power. It is equal to 80 MHz repetition without any distortion or decline of laser beam quality. To be more precise, the fiber laser system has been already tested and test results demonstrate a small heating effect.

Moreover, the researchers claim that the use of more amplifier channels results in laser beam power scaling up to the 100-kW level. The fiber laser’s applications include such extreme fields as laser-driven particle acceleration and space debris removal in addition to material processing.

There are also other applications, for instance, high-speed scanning and ablation cooling. Herewith, the developed fiber laser system is not ideal and still needs improvement. Nowadays the researchers plan to discover new applications at the high-power level and the transfer of the fiber laser technology.

The team of researchers pays careful attention to multicore optical fibers that provide the potential to transmit further superior performance in simpler and compacted laser systems. If you are looking for a compact highly-efficient laser system, the Optromix company is ready to manufacture it.

Laser beam pulses make optical fibers act as gun

A team of researchers from the U.S. has developed a new fiber laser technology that allows for stimulating the emission of electrons from the tip of an optical fiber by a laser beam pulse passing through the fiber. It should be noted that according to previous researches, it is possible to use these nanotips of optical fibers as electron sources if they are stimulated by laser beam light. Nevertheless, this light had to be originated from an external source before.

To be more precise, now a light pulse from a fiber laser passing along the optical fiber can lead to the appearance of electrons instead of previous techniques. Such fiber laser technology provides more efficient nanoscale imaging and sensing applications making it possible to add electrons from previously challenging angles or locations.

For example, previously the optical fiber tips had to be tracked by laser systems, and this was considered to be more challenging technologically. Therefore, this problem limits the ability to tale images quickly and from any position. The promising solution is electron emission techniques that lowered the necessary laser beam power thanks to the proper design of the nano-scale tip of the optical fiber.

“If the optical fiber terminates in a tapered gold-coated nanotip of the correct dimensions, then the field intensity for a pulse of fiber laser light going through the fiber would demonstrate a distinct hot-spot at the tip, sufficient to stimulate electron ejection.” The fiber laser technology has been already tested on a femtosecond laser system to emit ultrashort laser beam pulses through an optical fiber with 50-nanometer-radius nanotip coated with gold film.

The test results demonstrate the appearance of controlled electron emission as the result of stimulation from the gold-coated nanotip of optical fiber. Additionally,  the electric field increases by specific wavelengths of laser beam light. Herewith, a similar result can be achieved with a less powerful continuous-wave laser system, if the voltage at the tip is enhanced to compensate it. 

It should be noted that this is the smallest laser beam intensity capable to cause electron emission from nanotips. Thus, nowadays it is possible to use a low-cost laser system instead of expensive ones.

Ultrafast fiber laser system for biomedicine

A team of scientists from India has demonstrated its new ultrafast yellow fiber laser system that has a compact size and generates high-power laser beams. It is possible to adjust the laser system that in turn provides perfect laser beam quality, resulting in the creation of a practical yellow light source generating ultrafast laser beam pulses.

To be more precise, fiber lasers with the yellow spectral range are considered to be very useful for definite medical procedures. Nevertheless, their wavelengths are generally produced by applying large and inefficient copper vapor laser systems, dye lasers, and optical parametric oscillators. 

Even though their application is wide, they have great disadvantages, for instance, “low level of average power, the lack of an optimal spatial laser beam profile, limited or no wavelength tunability, and broad output pulses.” The conversion of mid-infrared laser beam light into yellow one requires a two-step nonlinear frequency change, therefore, it can be adjusted from 570 to 596 nm. 

Herewith, such a wavelength range emitted by the fiber laser is regarded as a very potential for a variety of applications. This fiber laser system shows a reliable, high-power, ultrafast, adjustable yellow emission in a rather simple experimental configuration.

Additionally, the applications of such fiber laser technology include not only biomedicine but also full-color video projection and other numerous spectral fields thanks to a sought-after laser beam wavelength range. Nonlinear frequency conversion allows for changing mid-infrared laser beam light into yellow one that can be adjusted from 570 to 596 nm.

It should be noted that fiber lasers play a crucial role in numerous applications because they produce numerous photons in a short period to offer high-intensity levels and accuracy without arousing thermal damage. Moreover, nowadays there is no commercially available yellow laser system that offers the required parameters, and that would stand to gain from that wavelength range.

The use of ultrafast fiber lasers enables scientists to overcome the current limitations in a single experimental configuration. The laser beam frequency of the ultrafast mid-infrared laser system with a peak wavelength has been doubled in two various nonlinear crystals, herewith, the scientists employed not complex fiber optic components available in any conventional laboratory to reach a high-power, adjustable, ultrafast yellow fiber laser source.

The fiber laser system has been already tested and offered tunable ultrafast laser beam emission with significant average power promising for different applications, involving spectroscopy, material processing, and imaging. The laser system’s operation demonstrates high stability over a long duration.

Fiber laser systems produce low-cost bioelectronics

Nowadays it is difficult to imagine the modern world without the use of laser systems. They have significantly changed the current technique of material processing, fiber lasers’ application includes welding, cutting, marking, measurement sensing, 3D scanning, LIDAR devices, scientific researches, the fiber laser systems are widely applied in domestic appliances and even as laser beam weapons. Moreover, the applications continue expanding.

Laser systems are also employed in bioelectronics, however, their production is considered to be difficult and expensive. Nonetheless, a team of researchers from the U.S. has presented an easy, low-cost, and scalable technique that allows for producing bioelectronics elements applying fiber lasers.

The fiber laser technology can also be used in medicine, for instance, in pacemakers. The production principle is based on polydimethylsiloxane (PDMS) that is regarded as a type of elastomer (highly elastic, stretchable material). The use of a pretty low-cost commercial laser beam cutter makes it possible to change the PDMS into dense silicon carbide material required for electronics and even in bioelectronics.

It should be noted that previously, the researchers had to synthesize all the elements separately and then combine them. Now the fiber laser technology “enables sections of the soft PDMS to be turned directly into silicon carbide through accurate laser beam engraving to produce a seamless integration.”

To be more precise, it is easier to attach soft material to soft and deformable cells. Herewith, the silicon carbide systems are ideal for electronics, and it does not degrade within the body. Taking into consideration the requirement in high accuracy, the production by the fiber laser system is a very promising method for this application.

The laser system has been already tested on a tiny pacemaker made by the team. The researchers put the composite on a rat heart, to which electrical signals were employed. Therefore, the heart rate synchronized immediately to that of the fiber laser system.

Additionally, the researchers claim that other potential applications of laser systems are distinguished: they contain scientific measurement sensing or the stimulation of arterial smooth muscle cells. Laser beam light allows for directing signals to nearby cells, resulting in a targeted response and potentially supporting control over the contraction and relaxation cycles of muscle cells. Finally, it is planned to employ fiber lasers in “remote-controlling” arteries during muscle surgeries and treating patients with spinal cord injuries.

Low-cost crystal used in a fiber laser at room temperature

Recently a group of researchers from China has presented a stable laser beam generation process provided by a fiber laser system with a low-cost crystal at room temperature, therefore, the technology allows for solving the problem limiting such long operation.

To be more precise, high beam quality laser is considered to be a common device applied in various fields of application from manufacturing and research to communications and entertainment. Modern laser systems offer highly uniform laser beam light emission.

It should be noted that fiber lasers are generally classified by materials that enable researchers to transform energy into laser beam light with common components containing inorganic and organic semiconductors, gases, and crystals. Herewith, recent developments in fiber laser technology give the new potential to low-cost crystals in the application of laser systems.

The developed high beam quality laser has a pretty low cost and perfect stability, herewith, it generates various colors that can be adjusted. Nowadays it has been succeeded to solve the problem of stopping laser beam generation during constant operation at room temperature by paying careful attention to energetic states called triplet excitons.

The development of fiber laser systems based on organic semiconductors faces several obstacles such as losses generated by the buildup of triplets, which haven’t been examined sufficiently. The thing is that laser beam energy includes usually positive and negative charges resulting in an exciton (a combination of opposite charges).

“Excitons are frequently observed in organic semiconductors and, because of quantum mechanics considerations, most often fall into two types termed singlets and triplets, with light emission being nearly impossible for triplets.” The researchers claim that triplets with long lifetimes are responsible for stopping of fiber laser system generation.

These triplets cause laser beam energy loss without producing light. Thus, the absence of these particles leads to solving the problem. The fiber laser technology has been already tested and demonstrated the opportunity to achieve a continuous laser beam process.

High beam quality laser contradicts laws of refraction

A team of researchers from the U.S. has presented a type of laser beam that contradicts the standard laws of refraction, thus, leading to new opportunities for forming the beam flow of a laser system applied for optical and laser applications. To be more precise, laser beam light generally slows up when it goes through a material.

Nevertheless, new high beam quality laser emits light that does not change the speed at all resulting in the possibility of a laser beam to pass at various points in space at the same time. The operating principle of such a high beam quality laser is based on a spatial light modulator that changes the energy of the laser beam pulse to combine its properties in space and time.

The fiber laser technology developed enables the researchers to monitor the group speed of the laser beam pulse. “When a pulsed laser beam was given accurate spatiotemporal spectral correlations, it demonstrated refractory phenomena such as group-velocity invariance concerning the refractive index, group-delay cancellation, anomalous group-velocity increase in higher-index materials, and tunable group speed by changing the angle of incidence.”

It should be noted that the fiber laser technology has been already tested and the law of refraction was confirmed for spacetime wave packets that take into account these effects. Nonetheless, these properties of high beam quality laser contradict traditional laws of refraction. The researchers claim that one of the spacetime wave packets is always distinguished independently of materials through which laser beam light passes, herewith, it crosses two materials without changing its speed.

Thus, the medium properties are not important, that is why the laser beam will cross the interface and continue its operation. The thing is that the high beam quality laser does not influence the message speed, despite there are various types of materials. Pulses produced by the laser system can expand so that they arrive at various destinations at the same time.

This fiber laser technology is considered to be a new one offered a new concept for laser beam light. Therefore, such beams demonstrate the new behavior of laser systems and bring into question a build-in assumption. Finally, the team plans to examine the interaction of these new laser beams with tools such as laser systems and optical fibers, in addition to current data.

A new defensive fiber laser system

A company-manufacturer of laser systems for military applications from the U.S. presents a defensive system that can be mounted both in a pod and in a fairing. The thing is that the developed defensive fiber laser has been developed for the aircraft industry. A video has been shown and demonstrated two fiber laser systems: a pod installed under the centerline hardpoint, and a fixed device elevated in a fairing.

The operating principle of such defensive systems is based on fiber laser technology that applies an optical fiber as an active gain medium, compared to a solid-state laser system that employs glass or crystalline solid material. The main purpose of the fiber laser is the protection of air, sea and ground assets due to the opportunity to “reduce a threat at the speed of a lightning strike, the accuracy of a surgical scalpel, with the system that can deal with a swarm and with the scalable effect to be able to resist the threat.”

It should be noted that the fiber laser has the laser beam control system that allows delivering the laser onto the target, the pod installed on the tactical fighter jet to increase the laser beam power and cool the system. Moreover, such a fiber laser system can learn on adversary targets to suppress them. Even though the power of the system is not mentioned, specialists claim that it should be in the “tens of kilowatts” range.

Therefore, the laser system with such power enables army men to neutralize numerous air-launched missiles in flight. The developed fiber laser system for the military industry offers such benefits as self-protection against incoming threats, the ability to destroy several targets quickly, compensation for laser beam-spoiling transonic turbulence effects, compact size and reliable design, and the system is suitable for multiple aircraft types.

Herewith, the company also presented a 60 kW combined fiber laser that can emit a single laser beam of 58 kW. The laser system has not been yet tested because of technical challenges and complications caused by the coronavirus pandemic. Moreover, there are some concerns regarding the installation of such a huge laser beam system on an aircraft and its application to neutralize an adversary missile even from very close.
