Overcoming the limit of fiber lasers

According to a team of researchers from Australia, the coherence of laser systems can be significantly improved by overcoming limitations that are considered to be fundamental for 60 years. To be more precise, fiber lasers produce highly directional, monochromatic, coherent laser beam light.
It should be noted that the light is produced by the laser system as a narrow laser beam in a specific direction. Moreover, the wavelength and phase of every photon are equal. The coherence of a laser beam, in turn, is regarded as “the number of photons that can be emitted in this manner, which is a property crucial in determining the performance of a fiber laser in precision tasks like quantum computing.”
Herewith, a quantum limit of laser beam coherence is not a new phenomenon, and it was identified in the 1960s. Additionally, there is a theory that the coherence of the fiber laser system is less than the square of the number of photons. Nevertheless, the researchers suggest a way how laser beam energy is added to the system and how it is released to create the beam.
Even though these suggestions are right and suitable to most standard laser systems, they are not obligatory when it comes to quantum mechanics. The ability of researchers to develop and control quantum systems has transformed the conception of what is practical. Additionally, numerous researches allow for a better understanding of quantum processes occurred in fiber lasers.
Nowadays the team of researchers from Australia has applied numerical simulations to show that it is possible to overcome the limitations of fiber laser systems. The fiber laser technology has been already tested and demonstrated that the laser beam coherence is less than the fourth power of the number of photons.
Therefore, when the stored number of photons in the fiber laser is large, as is generally the case, the novel upper limit is much higher than the old one. Also, the researchers have developed a quantum mechanical model for a fiber laser system that could reach this upper limit for coherence in a theory.
Finally, more time is required to create a super laser system. However, this fiber laser technology approves that the production of quantum-limited fiber laser is possible employing the superconducting technique. Herewith, such a technology is also applied in the modern best quantum computers.
The developed fiber laser may have applications in that field. Thus, new fiber laser systems allow for expanding new applications and promoting new researches into more energy-efficient laser systems.

Laser beams control nanomotors

Laser systems become an integral part of human life, herewith, fiber laser technology continues to develop leading to the appearance of new applications and expanding the old ones. For instance, a team of scientists from Japan has presented novel linear nanomotors that can be moved in controlled directions applying laser beam light.
To be more precise, these fiber lasers used in nanomotors make it possible to develop new microfluidics and lab-on-a-chip systems with optically actuated pumps and valves or other devices based on fiber laser technology that can be previously challenging or even impossible perform.
It should be noted that nanoscale devices greatly differ from the one involving the contraptions to which researchers have used to employ. For example, it is more challenging to produce and accurately control a nanomotor (the tiny motor that is smaller than a bacterium) based on the laser system than to drive a car.
The recent development of the Japanese team includes a fiber laser system used in linear motors nade from gold nanorods that allow for moving in a controlled direction when subjected to a laser beam light. Herewith, the operating principle reminds a sailboat that can be directed in any desired position.
Such nanomotors’ operation does not lead to follow the direction of the laser beam. Their operation is based on the orientation even when they are subjected to a laser beam emitting from another angle. Thus, the laser system moves dut to the lateral optical force produced by the sideways scattering of laser beam light from the particles.
Moreover, there is no need to direct or shape the laser beam with lenses, which was quite challenging previously. Additionally, compared to previous systems, the wavelength of light produced by the fiber laser does not influence and limit the size of new nanomotors.
Therefore, the laser beam or the field gradient does not define the motion and does not restrain it, the direction is based on the orientation of nanoparticles themselves. “The key to this fiber laser technology is the localized surface plasmon resonance – collective oscillations of free electrons – within periodic arrays of nanorods.” They emit scattered laser beam light in a particular direction.
The team of scientists plans to apply this fiber laser system to develop a new platform for nano-sized devices with moving parts that follow predetermined paths while being directed by unfocused laser beams. Thus, they claim the cost and complexity of such systems can be significantly reduced while accuracy and robustness will increase.

A twice thinner fiber laser scalpel

Fiber laser as a scalpelA team of researchers from Taiwan and Russia has presented a new scalpel based on fiber laser technology. Herewith, such a fiber laser scalpel is twice thinner than conventional ones. Taking into account the fact that standard medical scalpels have different shapes for specific tasks, the new laser system provides numerous benefits.
To be more precise, the researchers have developed a scalpel based on a fiber laser system that allows for decreasing its thickness by half. The researchers claim that the created curvilinear shape opens numerous opportunities for fiber laser application in medical fields.
The team from Taiwan and Russia produces a laser beam “blade” applied in a medical scalpel with a given curved shape employing a photonic “hook”. The thing is that nowadays “there are laser beam scalpels only with an axisymmetric focus area, that is, their blade is cylindrical.”
It should be noted that another blade shape enables the researcher to open new applications of the laser system in medicine. Additionally, this fiber laser scalpel is two times thinner than the cylindrical shape. Therefore, specific tasks require various shapes of standard surgical scalpels.
For instance, it is possible to cut or remove tissue by a scalpel based on fiber laser technology. The operating principle is based on the laser beam with increased temperature in a limited range up to 400°С. Thus, the fiber laser system burns out the beam, while tiny blood vessels along the cut edges are sealed.
Moreover, the fiber laser scalpel provides incredible advantages, for example, the incisions made by it are pretty thin and the radiation is not dangerous. The researchers have succeeded to bend the laser beam by the installation of an amplitude or phase mask at the end of the optical fiber.
The mask in the fiber laser system is regarded as a small plate made of metal or dielectric material, for example, glass. The laser beam energy inside the optical fiber is redistributed by the mask leading to a curved part of radiation localization at the end of the fiber (the so-called photonic hook).
The fiber laser system has been already tested and demonstrated that the curved blade had a length of up to 3mm. Herewith, the thickness of the laser beam blade reaches 500 microns (slightly bigger than a diameter of a human hair). Such test results make the fiber laser scalpel perfect for surgeries.

Ultrafast coherently combined fiber laser technology

Recently a team of researchers has succeeded to develop the new ultrafast fiber laser technology due to coherent laser beam combination with direct water cooling. The thing is that the laser system produces an average power that is virtually 10× that of current high-powered fiber lasers combining the output of 12 amplifiers.
To be more precise, such a combination allows for fiber laser systems to overcome any challenges presented by the waste heat that they create when emitting laser beam light. It should be noted that current laser’s parameters enable them to effectively dissipate waste heat (in the range of a single kW) but the exit beyond that range of power leads to the decrease of laser beam quality.
Herewith, the new fiber laser system emits 10.4 kW average power, at 80 MHz repetition, without any decrease of laser beam quality. The operating principle is based on the laser system that “is turned on and optimized channel-by-channel, with each channel performing at maximum pump power.”
Additionally, the fiber laser has been already tested and demonstrated 96% combined efficiency with a laser beam pulse energy of 130 μJ and pulse energy of 250 fs. Thus, the problem of high noise has been overcome in the early-stage thanks to direct water cooling resulting in a highly reliable laser system.
It should be noted that in the development stage, the fiber laser demonstrated excellent performance at low average laser beam power for deactivated water cooling. Nevertheless, when the cooling is activated, the level of noise increases and requires the cooling system. Therefore, the amplifier layout has been changed leading to solving the existing problem.
Also, the researchers claim that the new fiber laser technology makes the system close to ideal laser beam quality that is considered to be equal to 1. It is very important because the aim of the development is the solution to the heat-induced problem of laser beam quality decrease of individual amplifiers.
The coherent beam combination makes it possible to unite several high-powered laser beams into one, and the power and beam quality remains the same while increasing brightness. This fiber laser can be used in extreme applications, for example, laser-driven particle acceleration and space debris removal. Additionally, this laser system is ideal in industrial and manufacturing industries, for instance, in high-speed scanning and ablation cooling.
Finally, the fiber laser system has a sealed housing that prevents it from dust contamination during the operational process.

Micro comb laser systems as variable microwave devices

Low-noise signals play a crucial role in various applications, for instance, high-speed telecommunication and ultrafast data processing. Usually, huge and sensitive microwave oscillators emit these signals, however, these systems can not be applied out-of-door. The promising solution is the application of high-quality pulsed laser systems based on micro comb technology.
To be more precise, such fiber lasers offer the high optical frequency and spectral purity of laser beam fields, herewith, they produce low-noise microwaves compactly and efficiently. Nonetheless, these laser systems emit microwaves with limited frequency adjustment, that is why conventional resonator has to be huge and has difficulties in tunability.
A team of scientists from Dublin has presented a novel fiber laser technology for producing different low-noise microwaves with a single system. According to this technology, a microresonator frequency comb is installed into a compact laser system, whose “intensity  is modulated by an off-the-shelf microwave oscillator.” 
Thus, it is possible to emit new laser beam microwaves with tuned frequencies by forcing the modulation frequency to tightly follow a subharmonic frequency of the microwave. Moreover, these microwaves provide lower phase-noise than fiber laser systems used previously for the same purposes.
It should be noted that such a fiber laser technology is a frequency division that allows for delivering the frequency purity of an optical signal into the microwave domain. Herewith, it is possible to deliver the spectral purity between various microwave signals. Despite it is challenging to perform ideal laser beam microwave frequency division in a tunable way, the fast-modulated fiber laser allows for making it by employing cost available photodetector and a moderate control system.
This laser system produces a secondary frequency comb with more densified spectral emissions leading to numerous spectroscopic applications. Additionally, the main elements of the system, for example, the microresonator and the semiconductor laser system are considered to be discrete and connected with lengthy optical fibers.
The team now continues working on integrating and advanced-packing the system. The thing is that the opportunity to make the device smaller and its mass production leads to the revolution in the market for portable low-noise microwave and frequency comb tools thanks to fiber laser systems.

Space fiber laser system passes tests in orbit

The company-manufacturer of space facilities Space X has presented the successful test results of their “space” fiber laser systems. To be more precise, these laser systems allow for providing optical (laser beam light-based) communication with a significantly high bandwidth ceiling that is a potential way to offer the wireless, high-speed transmission of huge data information over long distances.
The members of Space X claim that about 650/715 satellites are operational, herewith two spacecraft are equipped with prototype fiber lasers, and their test results are regarded as very successful. Such a fiber laser system has the biggest benefit for connection that includes a significant reduction in connection latency.
The thing is that “by moving a great deal of the work of networking into orbit, the data transmitted on an interlinked satellite network with the help of laser beam light would theoretically need for much less routing to achieve an end-user, physically decreasing the distance that data has to travel.”
Even though the speed of laser beam light is pretty fast (about 300,000 kilometers per second), however, the limitations of current fiber optic cables result in difficulties in routing data to and from opposite ends of the planet. Thus, the space fiber laser provides the network that can serve individual users 100 Mbps of bandwidth.
The realization of full connection potential requires high-performance laser systems compared to standard fiber optic cables resulting in internet service that overcomes the existing fiber options. Space fiber laser helps to avoid the connection dropout scenario making the fiber laser technology ideal for space applications.
For instance, in the case of finding customers without a ground station in reach by an active satellite, those forlorn data packages will be directed by the fiber laser system to another satellite with immediate ground station access. Therefore, the connection becomes better, and enough optimization makes it possible to direct user communications by the space fiber laser to and from the ground stations physically nearby to the user and their traffic destination.

Industrial fiber laser system produces attosecond laser beams

A team of scientists from the U.S. has presented a new fiber laser technology that allows for industrial laser systems to emit attosecond laser beam pulses. It should be noted that usually, attosecond science presents several difficulties because it is based on world-class fiber laser devices.
Thus, the opportunity to apply industrial laser systems instead of complex devices that need huge laboratory tools and cleanroom environments enlarges new possibilities resulting in higher accessibility to researchers from all spheres. The generation of short laser beam pulses required for attosecond research needs the light to be directed through tubes filled with noble gases (xenon or argon) to compress them in time.
The scientists claim that nonlinear compression performed by the fiber laser is considered to be efficient when driven in molecular gases, employing laser beam pulses substantially longer than a few cycles, because nonlinearity is increased. The fiber laser technology has been already tested, and the scientists have succeeded to compress about 100-cycle laser beam pulses generated by an industrial fiber laser system by applying molecular gases – nitrous oxide in the tubes leading to changing pulse length.
Such laser systems allow for simultaneously drive molecular alignment and supercontinuum generation in a gas-filled capillary. Moreover, these single-cycle laser beam pulses are regarded as possible to achieve with this fiber laser technology. Thus, industrial laser systems that can be easily bought at an appropriate accessible price now are applied to emit attosecond pulses.
The thing is that the choice of gas and durations of the laser beam pulses plays a crucial role. For example, the use of molecular gas results in an enhanced effect. Therefore, the choice of gas is “important since the rotational alignment time depends on the inertia of the molecule, and to maximize the enhancement we want this to coincide with the duration of our pulses generated by the fiber laser.”
The development of fiber laser technology makes the system adjustment simpler promoting the operation with a wide variety of laser systems with various parameters. The research of attosecond science is regarded as very promising because such fiber lasers make it possible to construct images of the electrons, herewith, study the fast motion of electrons inside atoms.

Fiber laser systems act as weapons in military application

Nowadays technological progress has reached a milestone when laser system weapons installed on vehicles have become a reality. Vehicle-mounted laser beam weapons are considered to be a low-cost device for improving combat capabilities, applied by both regular and irregular armies involved in almost every conflict in the world. 
Until recently, options for installing weapons on combat vehicles have been limited to machine guns and artillery systems of various types. However, the situation here begins to change with the emergence of fiber laser systems or directed laser beam energy systems that produce enough power to burn small aircraft and ammunition in the air. 
The placement of large power storage units on such systems has always been a serious problem, but recent developments in fiber laser technology have reduced the size of lasers to allow them to be installed even on a large jeep. 
In the 90s, there was a technological revolution in fiber optic communications, which accelerated the development of high-power solid-state laser systems, which found application in industrial processing a decade later – branding, cutting, welding, and melting.
These laser systems are extremely effective at short distances, but it was a matter of time for the industry to find a way to scale this fiber laser technology and develop futuristic weapons that could cut and melt targets at a distance of several hundred or even thousands of meters.
Interest in military applications of fiber lasers increased immediately after the demonstrations of the first quantum generators. The unique properties of laser beam radiation, directivity, monochromaticity, coherence, generation of ultrashort pulses, and high energy concentrations are regarded as very attractive for various weapons systems. 
Laser systems include devices employed to perform measurements and even functional sensors. For military applications, such fiber laser systems are applied for guidance or target designation, rangefinding (determining the distance to the target), control of combat vehicles (proximity sensors), detection, tracking, and visualization of targets (laser beam radars), countering enemy electronic-optical tools. 
Fiber laser weapons always cause a lot of controversies. Some people consider it a weapon of the future, while others categorically deny the likelihood of effective examples of such weapons appearing shortly. People thought about laser beam weapons even before they appeared.
Since the development of the first laser system, a huge number of ways to obtain laser beam radiation have been found. There are solid-state lasers, gas lasers, dye lasers, free-electron lasers, fiber lasers, semiconductor lasers, and other laser systems
Also, lasers differ in the method of excitation. For example, in gas laser systems of various designs, the active medium can be excited by optical radiation, electric current discharge, chemical reaction, nuclear pumping, or thermal pumping. The emergence of semiconductor lasers leads to DPSS (diode-pumped solid-state) laser systems.
Various designs allow obtaining different wavelengths of laser beam radiation at the output, from soft x-ray radiation to infrared radiation. Laser systems that emit hard x-rays and gamma-ray lasers are still in development. This allows selecting the fiber laser based on the problem being solved. 
As for military applications, this means, for example, the possibility of choosing a fiber laser system with wavelength radiation that is minimally absorbed by the planet’s atmosphere. Since the development of the prototype, the power has continuously increased, the mass and size characteristics and the efficiency of lasers have improved. 
This is very clearly seen in the example of laser modules. Of course, fiber laser modules are not suitable for creating combat lasers, but they are in turn used for pumping efficient solid-state and fiber laser systems
An important element of the system is the high-quality laser beam focusing system – the smaller the spot area is on the target, the higher the specific power is that allows damage to be caused. Progress in the development of complex optical systems and the emergence of new high-temperature optical materials allows producing highly efficient focusing systems. 
Another important component that makes it possible to create a laser beam weapon is the development of systems for aiming and holding the beam on the target. Gigawatt power is required to hit targets with an “instant” shot, in a fraction of a second, but the creation of such fiber laser systems and power sources for them on a mobile chassis is a matter of the distant future. 
Accordingly, it is necessary to hold the spot of laser beam radiation on the target for some time (from a few seconds to several tens of seconds) to destroy targets with lasers of hundreds of kilowatts – tens of megawatts. This requires high-precision and high-speed drives that can track the high-quality laser beam on the target, according to the guidance system.
The guidance system must compensate for the distortion introduced by the atmosphere, when shooting at long distances, for which the guidance system can use several laser systems for various purposes, providing accurate guidance of the main “combat” laser beam on the target. 
Because of the lack of power sources for optical pumping, gas-dynamic and chemical laser systems have received priority development in the field of weapons. Despite all the benefits provided by gas-dynamic and chemical lasers, they have significant disadvantages: the need for consumable components, launch inertia (according to some data, it is up to one minute), significant heat generation, large dimensions, and the output of spent components of the active medium. Such lasers can only be placed on large areas.
At the moment, the greatest prospects are for solid-state and fiber laser systems, which only need to provide them with sufficient power to operate. The US Navy is actively working on free-electron fiber laser technology. An important advantage of fiber lasers is their scalability, i.e. the ability to combine several fiber laser modules to get more power.
Modern laser systems adapt to any vehicle that you want to use at the moment and that’s why this technology is so impressive, it provides the flexibility of the architecture to fit different vehicles without much refinement. This allows developing a system to support both a combat team and a forward operating base.
The system applies commercial fiber lasers assembled into easily reproducible modules, which makes it very affordable. Using multiple fiber laser modules also reduces the likelihood of minor faults, as well as the cost and volume of maintenance and repair.
There are several characteristics of a directed energy tactical weapon that make it very attractive to modern armed forces, including the low cost of “ammunition” and their speed, accuracy, and ease of use.
First of all, this is a very accurate weapon with potentially very low indirect damage. The speed of laser beam light allows instantly irradiating the target, and, therefore, it is possible to hit highly maneuverable targets, i.e. keeping the laser beam on the target, which sometimes can not cope with kinetic ammunition.
Perhaps the most important benefit of such fiber laser systems is the low cost of one effective “shot”. For instance, at this point, you don’t want to spend expensive and powerful defensive kinetic weapons on cheap multiple threats. Laser beam weapons are regarded as an addition to kinetic systems. 
The laser system is used against a large number of cheap threats of low intensity, leaving your kinetic force for attacking complex, armored, long-range threats. Such fiber lasers can be employed to protect against flying drones. For example, an American company has introduced a laser system to protect objects from drones. 
A combat laser system shot down five aircraft-type drones during tests in 2017 in New Mexico. The fiber laser system is called ATHENA (Advanced Test High Energy Asset, high energy system for advanced testing). The operating principle is based on a 30-kilowatt fiber laser.
Another application of the laser system was demonstrated using a fiber laser system against missiles.  A message published on the company’s website informs that the engineers have managed to solve the issue related to the heating of the high-quality laser beam installation, as well as its compactness, thus, creating an ideal protection system. 
The engineers claim that this is the only company that has an integrated fiber laser weapon system at an acceptable level of power and accuracy, which they have achieved with the ADAM (Area Defense Anti-Munitions) and ATHENA (Advanced Test High Energy Asset) laser systems.

Fiber laser systems for metal cutting: a short overview

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.

High-powered fiber laser systems provide geothermal drilling

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.
