Fiber laser systems promote product technologies

Such advantages of fiber lasers as throughput, reliability, and low operational cost make laser systems a powerhouse in the manufacturing industries where it is necessary to cut, weld, mark, and micromachine materials. Herewith, fiber laser systems differ from traditional industrial lasers by their unique features. For example, high-power single-mode laser systems and widely flexible pulsed fiber lasers allow solving various process challenges by electronic control of operating parameters.

The principle of fiber laser operation is based on converting relatively low-brightness pump light emitted by laser diodes into high-brightness output, where the output laser beam quality is often the only spatial mode enabled by the physics of the fiber laser system design. The uniqueness of fiber lasers among other types of lasers includes such features as a sealed optical cavity and a single-mode, guided-wave medium.

It should be noted that a sealed optical path in modern fiber laser systems provides immunity to environmental contamination and enables not to carry out any adjustment. High-power laser system’s components include single-mode laser modules into high-brightness delivery fiber in fused fiber combiners. Thus, fiber lasers are considered to be a highly reliable laser technology that offers minimal variation over time and temperature.

The thing is that the use of sealed pump diodes and non-darkening fiber optic technology creates a laser system that is possible to be used continuously in production for years without any adjustment or degradation. For example, numerous industrial manufacturers use fiber lasers or disk lasers for metal cutting and welding because of the practically equal power, laser beam quality, wavelength, reliability, and beam delivery options.

The most common applications of fiber laser systems include high-speed remote welding because there is no need for the contact process during laser system welding, that is why the laser technology includes no tool wear. Additionally, fiber lasers allow the joining of various materials due to the brightness and dynamic capabilities of laser systems that were considered to be unweldable before.

Also, now it is possible to employ the same fiber laser in the same optical configuration for a different range of materials processing applications by simply controlling both the laser beam pulse parameters and the scanhead toolpath. One more laser application is cleaning and drilling that were a real challenge for industrial laser systems because they had to deal with a significant variation of target materials.

Therefore, such qualities of modern fiber lasers as the brightness, stability, and flexibility extend the present material processing applications and create new ones. Fiber laser technology is perfect for manufacturing with identical laser beam properties from unit to unit, with no field adjustment or maintenance.

Fiber Optic Sensors find cancer biomarker

A team of researchers from the Netherlands has developed chip-based fiber optic sensors with integrated laser systems to allow finding low levels of a cancer protein biomarker in a urine sample. Such fiber sensing technology is considered to offer more sensitivity than previous techniques, resulting in noninvasive, inexpensive fiber sensing ways to identify molecules that are responsible for the presence or progression of a disease.

To be more precise, such a fiber optic sensor enables researchers to make label-free detection of S100A4 that is regarded as a protein connected with human tumor development at clinically relevant levels. According to the team, fiber sensing technology promotes faster and more sensitive findings of tumor biomarkers, which favor faster treatment and better results.

The principle of fiber sensor operation is based on “the detection of specific molecules by illuminating the sample with an on-chip microdisk laser system, made with aluminum oxide”. Thus, it is possible to use aluminum oxide doped with ytterbium ions to manufacture a fiber laser that emits in a wavelength outside the laser beam light absorption band of water, while still allowing the accurate finding of biomarkers. Herewith, the frequency or color of the laser beam changes in a detectable way when there is its interaction with the biomarker under consideration.

The laser pump light equipped with the fiber optic sensor performs lasing in a micron into the resonator. Herein, fiber probes are held on the resonator surface capturing the required analytes. Then the laser beam in the ring goes through the fluid, and the attachment of required analytes shows the frequency shifting of laser system emission. Finally, it is possible to accurately measure this shift allowing the detection of minute amounts of analytes flowing over the fiber sensor in a “specific” way.

Despite the fact that fiber optic sensors that monitor laser frequency shifts are not novel, they are often regarded as not easily installed on small, disposable photonic chips, while aluminum oxide can be easily manufactured monolithically on-chip, herewith, it is compatible with conventional electronic manufacture procedures. Such fiber lasers enlarge their opportunities due to unprecedented sensitivity because of much narrower laser beam linewidth than the resonances of passive ring resonators. When other noise sources are overcome, this fiber sensing will enable the finding of minute frequency shifts from biomarkers at very low concentrations.

The developed fiber optic sensor has been already tested in complex liquids such as urine resulting in the detection of S100A4 at concentrations as low as 300 picomolar. Nowadays it is planned to integrate all the relevant optical sources and signal generation components onto the chip to make the fiber sensor even simpler to operate.

Laser Beam diodes create deep-UV light

A team of scientists from Japan has manufactured a laser beam diode that allows emitting deep-ultraviolet light. To be more precise, the developed laser system can produce the shortest laser beam wavelength in the world, it is only 271.8 nm under pulsed current injection at room temperature.

It should be noted that previous versions of similar fiber lasers succeeded to achieve emissions only down to 336 nm. The potential applications of the new laser system include disinfection in health care, treating skin conditions, for instance, psoriasis, and analyzing gases and DNA.

The base of the fiber laser system is made of a high-quality aluminum nitride (AlN) substrate that enables to escape of the limitations connected with lower quality AlN. The thing is that the AIN quality is considered to influence the efficiency of a fiber laser diode’s active layer in converting electricity into laser beam light energy.

The team confirms that a quantum well separates p-type and n-type layers in the laser system. The operating principle of the developed fiber laser is based on “electric current that is passed through a laser beam diode, and positively charged holes in the p-type layer and negatively charged electrons in the n-type layer flow toward the center to combine, releasing energy in the form of photons.”

Thus, scientists have developed the quantum well for the fiber laser so that it could produce deep UV light. The p- and n-type layers consist of aluminum gallium nitride (AlGaN). Herewith, every side of the p- and n-type layers in the laser system are surrounded by cladding coatings made of aluminum gallium nitride as well. The cladding is produced by using the process of doping.

Doping is regarded as a way that changes a material’s properties. The team also claims that the aluminum gradient of laser beam diodes increases the flow of positively charged holes. Finally, it was discovered that the technique of the polarization doping of the p-side cladding layer implied that a pulsed electric current of “remarkably low operating voltage” of 13.8 V in the fiber laser system was required for the emission of the UV wavelength.

Nowadays the team of scientists plans to perform advanced joint research to reach continuous room temperature deep-UV lasing for the production of UV-C semiconductor laser system products that can greatly improve the current benefits leading to the appearance of new promising applications in various areas.

Temperature control is crucial for the fiber lasers industry

Thermal stability plays a crucial role in industrial laser systems. Thus, the developers and manufacturers of fiber lasers have to design them to provide accurate heat regulation. Because inappropriate temperature control can lead to systemic or catastrophic consequences. The thing is that fluctuating temperatures significantly influence the capabilities of fiber laser systems and their lifespan, as well as production outcomes and customer satisfaction.

The risk of premature failures on laser systems increases, to be more precise, in the case of low-temperature control (when electronics are not being cooled properly). Numerous fiber lasers have water-cooled systems (the chiller), and the laser stops operating when any of those components go down. New chiller technologies have been developed to produce a more reliable chiller that fiber laser manufacturers can confidently install into all their systems.

The industry of chilling systems is considered to develop with the demands of the fiber laser industry. “Having a chiller that has the right heat removal, along with excellent stability and a level of quality and maintenance-free operation, is absolutely essential in keeping that fiber laser system up and running, so the customer’s making parts.” And power stability of laser systems is highly important for their reliable operation.

An ineffective chiller is going to have a great impact on a fiber laser with power stability. Additionally, it can influence the laser beam profile that can transform or warp things. In the case of water temperature increase, metal components of laser systems can be moving slightly more than it is required, and it can lead to the motion of the laser beam resulting in higher pointing instability.

The benefits of modern chilling systems for fiber laser systems include:

high quality;
less downtime;
ease of use.

Therefore, such innovations are required and vital in the evolution of the fiber laser industry. Some customers would not like to apply laser systems because of their maintenance that is regarded as the number one reason for failure. Nevertheless, now the problem is solved by a self-changing filter, due to which it is changed for up to two years.

New fiber laser technologies allow the development of a user-friendly recirculating chiller for various applications. Today it is possible to calculate the ideal pump, fluid, and power capacity for the chiller in fiber laser systems. Besides, the developers can produce a chiller considering your budget, herein, it will offer the highest value for customers.

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. If you are looking for a compact highly-efficient laser system, the Optromix company is ready to manufacture it.

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.

We manufacture laser modules using our technologies based on the advanced research work and patents of the international R&D team.

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.

We manufacture laser modules using our technologies based on the advanced research work and patents of the international R&D team. Laser processes are of high quality, high precision, easily-automated manufacturing solutions that provide repeatability and flexibility.
