Fiber Lasers for marking machines and 10 reasons to choose them

Fiber lasers are widely applied in many various spheres such as medicine, aerospace, etc. So there is no wonder that fiber laser machines for marking play an important role in businesses that require engraving or adding markings to their products. Nowadays, numerous companies insist on putting their logos or special markings, containing a crucial company or product’s information, to their item.

Main principles of fiber laser marking machines

It should be noted that the principle of fiber laser marking machines’ operation is based on the use of highly concentrated energy from light generated by a laser beam of high quality, then this energy obtained by such a fiber laser system allows creating an image or writing over a product’s surface.

Also, fiber laser machines for marking are considered to be quite useful because they apply the light from a laser beam as a way of a product’s identification. Compared to the previous identification technique that used paint and ink for marking, fiber laser technology based on concentrated energy by laser beam’s light produces markings that cannot be smudged or covered over. This is the main reason why the majority of companies began to use this fiber laser system-based solution for engraving logos and descriptions on their products.

Fiber Laser marking machines’ features

Herewith, fiber laser marking machines offer numerous other reasons why it is necessary to choose them for your business:

Fiber laser technology is a highly reliable and environmentally friendly solution;

Fiber laser marking is software-based, to be precise, the machine enables to engrave any letter or character;
Possibility to produce high-quality images on an object.

Fiber laser marking machines applications

Finally, these marking machines have numerous fields of fiber laser applications. For example, they are widely applied in the medical industry for manufacturing very specific medical tools. Fiber laser marking machines allows marking images, logos or even description on the medical devices that are subject of the sterilization process, herewith, the fiber laser technology does not influence the surface, consequently, it is safe to any patient.

One more fiber laser application includes marking the serial number of firearms that makes every item personal. Thus, it becomes easier to identify any firearm in the case of its stealing. Also, fiber laser marking machines are used for marking the serial number of each part of the industry during the manufacturing process.

Laser technology that can amazingly change human life

The word “laser” is considered to be a light amplification of stimulated emission of radiation. Laser technology is not only a scientific term or a “clever” word from sci-fi movies and TV shows but laser systems offer numerous laser applications that considerably have changed human lives over the last decades.

The principle of laser system operation is based on coherent light emissions. To be more precise, the light produced by a laser beam is emitted with spatial coherence. It means that the light of the laser beam remains narrow across long distances, herewith, it has a tight focus, while when it comes to the temporal coherence, then the light has a pulsed emission over a short period.

It should be noted that the first laser system was designed over fifty years ago, and at that time it was impossible to imagine the vast range of laser applications. Nowadays the development of laser technology allows carrying out various advances that bring profit to modern society.

The most widespread laser applications include the following:

- Medicine
  Today it is hardly possible to imagine the medical field without using laser technology, especially, the use of laser systems for cancer treatment and surgery processes. Additionally, there is an opportunity for therapy by lasers to combine with other treatment techniques to fight cancer. For example, laser systems are able to reduce or even destroy tumors that are close to the body surface.
  Laser modules made a great contribution to the surgical sphere, thus, the way to perform different procedures has been changed. For example, scalpels based on laser technology are widely applied for general surgery and procedures requiring more accuracy. Therefore, lasers for eye surgery can restore a patient’s eyesight back.
- Industry
  The application of laser systems in manufacturing includes cutting, welding, drilling, and engraving as well as the creation of smartphones, tablets, and LED TV screens with the help of laser technology. The efficiency and power of laser systems have revolutionized the global economy.
- Communication
  Optical fiber communication is one of the growing laser application areas. Lasers allow carrying out free-space optical communication, while traditional fiber optics use fiber cables. For example, laser systems offer communication among solar-powered satellites that are thousands of kilometers apart. Moreover, the use of lasers is not limited only by an industrial area and it continues growing.

Laser systems help in studying explosions

An explosion is considered to be a complex activity that is characterized by quickly changing temperatures, pressures, and chemical concentrations. There are special infrared laser systems called swept-wavelength external cavity quantum cascade tunable fiber lasers. They offer valuable and never-before-seen information about explosive fireballs.

This fiber laser device is versatile and includes such an advantage as a broad wavelength tuning range that enables it to measure numerous chemical substances as well as huge molecules in an explosive fireball. Researchers confirm that the capability of the laser system to measure and monitor the crucial changes during explosions will favor them to understand and even control the events.

The measurements by the laser system are performed with the help of rugged temperature or pressure probes placed inside an exploding fireball resulting in physical information. Nevertheless, the fiber laser device does not allow measuring chemical changes that may be created during the process of the explosion. Thus, it is possible to make a sampling of the donation end products by the tunable laser system. However, the data information will be presented only after the explosion is over.

The laser system is able to detect molecules in the fireball by controlling the way they interact with light, significantly in the infrared region. It should be mentioned that “these measurements are fast and can be taken a safe distance away”. Herewith, laser systems are essential for these purposes because fireballs are turbulent and contain highly absorbing substances.

The application of a new laser system device measures explosive occurrences at faster speeds, at higher resolutions, and for longer periods than it was possible before using infrared laser beam light. Therefore, now the swept-wavelength external cavity quantum cascade tunable fiber laser offers new measurements due to the combination of the best qualities provided by high-resolution tunable laser system spectroscopy and broadband fiber optic techniques such as FTIR.

The fiber laser system was tested on four types of high-energy explosives, all integrated into a specially developed chamber to contain the fireball. Herewith, a laser beam from the tunable fiber laser is directed through this chamber while quickly changing the laser beam light’s wavelength, then the light is recorded throughout each explosion to measure changes.

Finally, the detailed analysis of the information obtained by the laser system offers the required data about the temperature and concentrations of these substances throughout the explosive case. The tunable fiber laser opens a new way to study explosive detonations that could find other applications. Additionally, it is planned to extend the measurements due to the development of laser technology to more wavelengths, faster scan rates, and higher resolutions in the near future.

Laser technology for military applications

Nowadays U.S. Army Infantry receives high threats, while they advance through wooded, rocky terrain to maneuver to contact and “close with the enemy” resulting in facing the most incoming fire of any army unit. This is the main reason why the U.S. Army needs additional protection. The application of laser technology is considered to be a possible solution to the problem.

To be more precise, modern laser technologies can be implemented for the use of pre-shot detection, which means that such laser systems embedded in Army weapons would allow identifying enemy weapons before they are fired. The laser system can detect an optical part of a weapon (glass) directed at a military servant. It should be noted that such an opportunity for laser technology to see a person and detect a shot threat provides a great benefit.

Thus, according to researchers, the laser system technology allows soldiers to find their enemies without first being fired upon, leading to saving human lives and changing military tactics. Nevertheless, these portable laser system emitters are still in development. Herewith, the developed laser technology should be used along with the Army’s existing Rapid Target Acquisition system that applies wireless data links to connect night vision goggles with rifle weapons sights.

Additionally, the application of such laser devices by military servants offers numerous new combat benefits. For example, laser system weapons are used both as an offensive weapon and a “detector” capable of finding targets. Herein, there are scalable laser devices, which means that they are able to collect several laser beams or fire in more narrow configurations offering various options.

The application of the defensive laser system for detection may include soldier-fired offensive laser module weapons. The laser beams are very rapid (they travel at the speed of light), moreover, the laser devices are highly quiet. Therefore, it is possible to fire silently, allowing military servants not to give up their position.

In spite of the fact that weapons based on laser technology are in development stages, they are already used in the following fields of laser application: firing laser devices for army strykers, the weapons system for the Navy, ground-testing laser weapons for the Air Force. A potential application of the laser system includes missile defense and armed drones engineered for space flight.

The use of laser technologies for military purposes has several developmental challenges. The thing is that mobile power sources are required for laser systems to operate, also portable laser devices pose some technical challenges which are necessary to be improved.

Ultrafast fiber lasers for smart cloth

Recently waterproof energy-storing cloth for smart garments was developed on the basis of carbon dioxide and ultrafast fiber lasers. Researchers from Australia offer cost-efficient and scalable fiber laser technology that allows fast fabricating textiles with energy-storage devices installed inside them. The technology-based on CO2 laser system and ultrafast laser can produce a 10 × 10 cm smart-textile patch that has such benefits as waterproofing, stretchability, herewith, it can be easily integrated with energy-harvesting technologies.

To be more precise, the fiber laser technology promotes graphene supercapacitors (energy-storage devices) to be printed by laser systems directly onto textiles such as nylon. The principle of the technology is based on the combination of a supercapacitor printing by a fiber laser and a photovoltaic cell to create an efficient, washable, self-powering smart fabric. Additionally, the researchers confirm that such a laser system is able to overcome the main disadvantages of current e-textile energy-storage technologies.

It should be noted that the popular smart-fabrics industry finds numerous laser applications in wearable devices for “the consumer, healthcare, and defense sectors, including monitoring vital signs of patients, tracking the location and health status of soldiers in the field, and monitoring pilots and drivers for fatigue”. The most widespread laser system application is considered to be laser lithography.

The thing is that the researchers put an elastomer solution (polydimethylsiloxane) on one side of nylon textile while a solution of graphene oxide and binder is coated onto the other and dried to form a film 3 μm thick. Then CO2 laser and femtosecond laser are used to form the fabric. The carbon laser performs photothermal reduction, while the ultrafast fiber laser achieves a combination of photothermal and photochemical reduction. Thus, the researchers succeeded to produce supercapacitor electrodes 10 μm thick over an area of 100 cm2 with an interelectrode distance of 80 μm with the help of fiber laser systems.

Herewith, the laser beam power of 4.5 W up to 8 W is used for the photoreduction process. Finally, the researchers discovered that after washing and drying the resulting graphene-enhanced cloth 50 times in commercial laundering machines, the electrical conductivity of the thin film, produced by CO2 and ultrafast fiber lasers, remains virtually unchanged compared with its initial state.

It is planned that the fiber laser technology allows real-time storage of renewable energy for e-textiles, as well as a faster roll-to-roll fabrication based on multifocal fabrication and machine learning techniques.

Laser Beams demonstrate a previously unseen matter phase

A team of researchers from the U.S. performs experiments with ultrafast laser beam pulses that allow creating a previously unseen phase of matter. For instance, adding energy to any material almost always changes its structure. However, new experiments by laser systems demonstrate the opposite: “when a pattern called a charge density wave in a certain material is hit with a fast laser beam pulse, a whole new charge density wave is created—a highly ordered state, instead of the expected disorder.”

The thing is that such laser technology may reveal hidden features in materials of all types. The researchers perform the experiment with ultrafast laser beam pulses by applying lanthanum tritelluride material that naturally changes into a layered structure. It should be noted that a wavelike pattern of electrons in high- and low-density areas creates spontaneously in the material, however, it is limited by a single direction within him.

Herewith, an ultrafast burst of laser beam light (less than a picosecond long) leads to the obliteration of the previous pattern and the creation of a new one. To be more precise, the novel pattern produced in the result of the laser system process is regarded as something that has never been observed before in this material. This pattern appears for only a flash, vanishing within a few more picoseconds.

It is not a discovery that matter can have two possible competitive states and that the dominant mode can suppress alternative modes. The laser technology, in its turn, reveals that different types of matter can have latent states lurking unseen if a technique is found to restrain the dominant state. It is possible to see by using ultrafast laser beam pulses at these competing states that are considered to have equivalent crystal structures due to the predictable, orderly patterns of their subatomic constituents.

The opportunity of laser systems that suppress other phases of matter may reveal completely new material features uncovering numerous new areas of application. This is the reason why it is highly necessary to discover material phases that can only be out of equilibrium. To be more precise, what is meant here are material states that would never be achieved without a technique, such as this system of laser beam pulses, for suppressing the dominant phase.

Traditionally, researchers transform chemical changes, or pressure, or magnetic fields to change the material phase, while now they apply laser beam light to perform these transformations. Finally, the results of laser technology may enable us to better understand the role of phase competition in other systems resulting in discovering higher-temperature superconductors and finding out why superconductivity appears in some materials at relatively high temperatures.

Laser Systems oscillators for more powerful fiber lasers

Physicists from Switzerland have developed a sub-picosecond thin-disk laser system oscillator that performs a record-high 350-watt average output laser beam power resulting in a new standard for the creation of more powerful fiber lasers. Herewith, ultrafast laser beam sources are at the center of fundamental scientific researches and industrial applications of fiber laser systems, including high-field physics experiments with attosecond temporal resolution to micrometer-accuracy machining of materials.

Nonetheless, repetition rates of several megahertz and average output powers of hundreds of watts remain still required from laser systems to put the envelope forward. The most promising way to perform such high-power laser beam sources is to produce them by increasing the power output from fiber laser oscillators rather than applying multi-stage amplifiers because of their complexity. The thing is that power increasing results in reliable and potentially cost-effective fiber laser systems.

The physicists have recently put the power-scaling approach to a new level. To be more precise, they offer a laser beam source that provides both the simplicity and high repetition rates of laser system oscillators with record-high average output power from this type of fiber laser. The researchers use a thin-disk laser system oscillator as the base, “where the gain medium, the material in which the quantum processes leading to lasing take place, is shaped like a disk of around 100 micrometers thin”.

The thing is that the shape of such laser systems provides a relatively big surface area that favors cooling. Nevertheless, thermal effects remain the main disadvantage because of which the record output laser beam power was considered to be at 275 watts. At present, several advances in thin-disk laser technology enable the physicists to reach an average output power of 350 watts, with laser beam pulses that are only 940 femtoseconds long, they have an energy of 39 microjoules and repeat at an 8.88-megahertz rate. It should be noted that these parameters are the subject of constant interest in both scientific and industrial applications.

Finally, the physicists have succeeded in the development of a technique that allows several passes of the pump laser beam through the gain medium without inflicting detrimental thermal effects, therefore, decreasing the stress on the relevant components. The opportunity to check thermal effects makes it possible to overcome the limitations of the 275-W level. Moreover, it is planned to use these laser system oscillators for the future achievement of 500 W or even higher.

Ytterbium Doped Fiber Lasers for spontaneous emission

A team of researchers presents a new random noise pulsed regime provided by a ytterbium doped fiber laser. Herewith, the output of the ytterbium laser complies with the photon statistics common to narrowband amplified spontaneous emission resulting in the noise pulsing in terms of probability density and autocorrelation functions. The new fiber laser technique demonstrates that the increase of ytterbium doped laser leads to a prominent decrease in the regime’s coherence time (from few ns to tens ps).

Fiber laser systems are regarded as highly promising tools that have a wide range of commercial applications. Fiber lasers are used as light sources in fully fiberized optical schemes with no free-space components. Herein, they offer a high level of optical and electrical to optical conversion efficiency. Additionally, fiber laser systems have various operating regimes, “characterized by narrow (from a tens Hz) to a very large optical band, in continuous-wave (CW) and pulsed regimes including Q-switched, mode-locking and soliton operations where the pulse width is ranged from hundreds of nanoseconds down to tens of femtoseconds”.

Ytterbium doped fiber lasers are considered to have such a benefit as an excellent power budget thanks to the absence of excited-state absorption. Nevertheless, ytterbium doped lasers have a disadvantage that influences their efficiency: there is a specific broadening of the laser line in the case when the cavity of fiber laser is made from FBG couplers. Thus, the partial leakage of fiber laser power occurs on highly reflective fiber Bragg gratings.
The output power of ytterbium doped fiber lasers may vary from several watts to tens kW or even a few hundred kW depending on single-mode and multimode operations. It should be noted that the low cavity Q-factor of ytterbium lasers causes high fiber laser gain, and the regime of the laser system is changed on random kW pulses resulting in Brillouin scattering.

The researchers confirm that the operation of ytterbium doped lasers happens in a noise pulse regime with random magnitudes and widths (not in the CW regime). Moreover, there is a dependence between the fiber laser photon statistics and laser beam power (and hence on laser linewidth), thus, its behavior seems similar to narrowband ASE. For instance, several high-amplitude noise events with low probability achieve powers more than the mean laser beam power.

Finally, the developed laser system has been already tested. It shows that the laser spectrum’s width becomes higher with increasing output power. While the rate of the ytterbium laser process at lower output powers is lower than at higher one. Taking into consideration the fact that the nonlinear optical fiber length is considerably shorter than the cavity one.

Fiber lasers have a fully tunable beam

The newly developed high-powered fiber laser provides real-time tuning of the laser beam characteristics directly from the output optical fiber using a fiber optic system. Laser systems have become indispensable tools for material processing, production, detection, protection, and scientific applications.

This success is based on improved laser performance in several areas, including average and peak power, wavelength range, timeline flexibility (pulse duration and frequency, complex signals), efficiency, power stability, long-term reliability, maintenance, and operational requirements costs.

High-powered fiber lasers were especially important for implementing some of these achievements and currently dominate in many areas of industrial production and microprocessing. In addition to the efficiency and reliability inherent in fiber lasers, fiber laser systems generally provide fiber delivery to the processing head, minimizing the load on the fiber optics in free space in the laser and the machine.

The opportunity to tune a laser beam is important, for example, when cutting metal (the largest industrial application), so a low-power beam with relatively high radiation quality provides the highest speed for thin material, but the maximum thickness is limited by the resulting narrow cut, which prevents melt removal.

A more powerful and more divergent laser beam (lower beam quality) allows cutting a thicker sheet with a corresponding reduction in speed compared to a thin sheet. During welding with high beam quality laser, welds with a “deep penetration channel” are formed, while larger spots with lower laser beam quality create shallow welds in the heat conduction mode, aesthetic welds on thin parts.

Besides, the specific shape of the beam affects the heat transfer and temperature gradients in the workpiece. Unlike a Gaussian beam, a flat-topped laser beam can prevent over or under processing by providing uniform radiation, and ring beams are known to improve processing quality in some applications.

Most laser systems provide the fixed characteristics of the beam. The laser beam can be converted to a different format using refractive or diffractive fiber optic systems. Fiber laser systems with a fixed beam can operate only in a limited range of processes or materials and thus, suffer from reduced productivity or limits.

Customizable laser beam characteristics would be highly desirable to ensure process optimization and tool versatility. Various approaches have been developed that provide a certain level of beam tuning, including zoom lenses, switchable diffractive optical elements, deformable mirrors, laser beam combiners, and (for fiber laser systems with a fiber radiation transport system) optical fiber connectors and switches with a motorized optics.

Extreme sound features of fiber laser systems

Diamond is regarded as a predominantly interesting material for this type of laser system for several main reasons. The thing is that it offers high thermal conductivity that promotes the development of compact fiber laser systems that have such features as high stability and high power. Herewith, such fiber laser has also a much higher level of sound speed compared to other materials. Therefore, new laser systems enable directly synthesize frequencies in the hard-to-reach millimeter-wave band.

A team of researchers demonstrates that the laser beam light-sound interaction is predominantly strong in diamonds, also they develop the first bench-top Brillouin laser system that applies diamonds. It should be noted that the result is awesome, the thing is that the new fiber laser offers a highly practical technique with a greatly increased range of performance. Compared to previous versions, the laser system with a diamond can operate without having to limit the optical or sound waves in a waveguide to increase the interaction.

To be more precise, it is easier to scale such fiber laser systems in size, they have much greater flexibility for monitoring the laser beam features as well as increasing power. Diamond opens new possibilities to use the unique features of Brillouin laser systems. Additionally, the fiber lasers result in numerous properties containing laser beam generation with ultra-pure and stable output frequency, the creation of new frequencies, and potentially, laser systems with exceptionally high efficiency.

The researchers confirm that the developed laser technology offers a new way to high-powered fiber lasers that are significantly efficient and have unique frequency features, for instance, low-phase noise and narrow linewidth. Such laser beam features play a crucial role in applications that require the highest standards of noise-free frequency properties, for example, ultra-sensitive detection of gravitational waves or manipulating large arrays of qubits in quantum computers.

Moreover, the diamond in laser systems allows synthesizing very clear frequencies beyond the microwave band. Thus, “as a consequence of the very high speed of sound in diamond—a dashing 18 km/s—the frequency spacing between the input pump laser beam and the laser line is many times higher than in other materials.” It is possible to produce frequencies in the millimeter-wave band (30-300 GHz) employing a technique called photo-mixing.

Finally, the fiber laser technology quantifies the strength of the light-sound interaction in diamond, a crucial parameter for predicting future design and performance resulting in the creation of a practical tool with over 10 W of laser beam power. Also, it is planned to expand the laser system abilities by offering fiber lasers with higher levels of frequency clarity and laser beam power required to maintain future progress in quantum science, wireless communications, and sensing.
