Application of fiber lasers in different industries

Fiber lasers are gradually replacing traditional lasers in laser marking, laser welding, laser cutting and other areas of dominant position.Today to explain the fiber laser in the field of advantage.

Application of fiber laser marker in industry

Industrial production requires high reliability, small size, quiet and easy to control. Fiber laser with its compact layout, light conversion to high, short preheating time, influence factors, maintenance free and easy and small fiber or by optical lenses composed of light guide system coupling strengths favored by people. Fiber lasers are gradually replacing traditional lasers in laser marking, laser welding, laser cutting and other areas of dominant position.

In the marking field, because of the high beam quality and positioning precision of fiber laser, fiber marking system is replacing Nd:YAG laser pulse marking system which is not obeyed by CO2 laser and xenon lamp.In Europe and Japan, for the big range hold, only in Japan, the monthly demand is higher than 100.According to IPG reported that, after the German BMW Motor Company purchased their high-power fiber laser, used in the door welding production line.

As the largest manufacturing country in the world, the demand for optical fiber laser marking machines is very large, and it is estimated that more than 2000 units will be needed every year.In the laser welding and cutting with the development of music category, or even a few million kilowatts kW fiber laser, fiber laser has also been used.

Application of fiber laser in sensing

Compared with other light source, fiber laser is used as light source sensor has many advantages.First of all, fiber laser has such advantages as high utilization, good tunability, compactness, compactness, light weight, convenient maintenance and good beam quality.Second, the fiber laser can be well coupled with the fiber, and is fully compatible with the existing fiber optic devices, and can be tested with all fiber.

Now, fiber optic sensing based on tunable narrow linewidth fiber lasers is one of the most popular applications in this field.The spectral linewidth of the fiber laser is very narrow. It has a very long correlation length and can modulate the frequency very quickly.The narrow linewidth fiber laser has been applied to the diffuse sensing system to realize ultra long interval and ultra high precision optical fiber sensing.Now, fiber optic sensing based on tunable narrow linewidth fiber lasers is one of the most popular applications in this field.China is expected to have more than 100 units of this kind of fiber laser every year.

Application of fiber laser in communication

Compared to other types of fiber laser, has obvious advantages in compact layout, heat dissipation, beam quality, volume and compatibility with the existing system, widely applied in the field of communications

Rare earth doped fiber as the gain medium of the mode-locked fiber laser can light pulse ultrashort high repetition rate, pulse width for the occurrence of picosecond or femtosecond lasing wavelength, and the optimal window falls in the optical fiber communication 1.55 M band, is the ideal light source of optical communication system in the future.Now, the mode-locked fiber laser with repetition frequency of 40 GHz and 10GHz has been developed.Once this communication network is deployed, the demand for this paradigm laser will be enormous.

Now, the mostly used for clinical laser argon ion laser, CO2 laser and YAG laser beam, but usually they are not high quality, has a very large volume of water cooling system, need to be huge, and the placement and maintenance is very difficult, which exactly is the fiber laser can be replenished.Because the water molecule has a absorption peak at 2 m, the 2 m fiber laser is used as a surgical operation, which can achieve rapid hemostasis and avoid the damage to the human body caused by surgery.

Novel Laser Design Offers Multi-Color Output

A cost-effective laser design that outputs multi-color lasing could improve information flow in optical fibers, and allow multi-color medical imaging of diseased tissue in real time. The laser has been engineered to control the color and intensity of the light by varying the cavity architecture. Researchers at Northwestern University demonstrated multi-modal nanolasing using plasmonic superlattices — finite arrays of nanoparticles grouped into microscale arrays — to support multiple band-edge modes capable of multi-modal lasing at programmed emission wavelengths and with large mode spacings. According to the team, access to more than a single band-edge mode for nanolasing was not possible previously because of limitations in cavity designs. By modeling the superlattice nanolasers with a four-level gain system and a time-domain approach, researchers showed that the accumulation of population inversion at plasmonic hot spots could be spatially modulated by the diffractive coupling order of the nanoparticle patches. Symmetry-broken superlattices were shown to sustain switchable nanolasing between a single mode and multiple modes. Nanoparticle superlattices integrated with liquid gain offer a platform to access different colors with tunable intensities, depending on the geometric parameters of the lattice. “In our work, we demonstrated that multi-modal lasing with control over the different colors can be achieved in a single device,” said professor Teri W. Odom. “Compared to traditional lasers, our work is unprecedented for its stable multi-modal nanoscale lasing and our ability to achieve detailed and fine control over the lasing beams.” The research provides a strategy for eliminating costly fabrication processes and directly producing multiple, stable lasing peaks from a single device. Currently, multi-color lasing output is only possible by putting together many single-color lasers. “In humans, our perception of the world would be limited if we only ‘saw’ in a single color,” Odom said. “Multiple colors are essential for us to receive and process information at the same time, and in the same way, multi-color lasers have the potential for tremendous benefits in daily life.” In the future, Odom said she and her team would be interested in designing white nanolasers by covering blue, green and red wavelengths simultaneously, and changing the “whiteness” by controlling the relative intensity of the blue, green, red channels. The research could open possibilities for ultra-sensitive sensing in chemical processes, where different molecules could be monitored simultaneously; and in-situ cellular imaging at multiple colors, where different dye labels could be excited by different laser colors correlating to different biological processes.

New laser technology --ultra fast laser

Ultra fast laser applies to diamond, sapphire, glass, semiconductor, metal, polymer and other materials precision fine machining.  

Origin

Let the time back to the 1980-1990 era, then all optical scientists in the laboratory of painstaking design, adjustment of ultrafast laser transmission, focusing, try to irradiation on a variety of materials, in order to find the moment of arrival (they actually found a large number of unusual phenomena), they don't think twenty or thirty after years of ultrafast laser processing workshop has quietly entered the consumer electronics factory, entered the hospital to carry out precise eye surgery, a key ring into the sophisticated components manufacturing.

Today, many people around the world are beginning to rely on ultra fast lasers because they can do many jobs that conventional methods do not.

Application

Ultrafast laser called ultrashort pulse laser, its main characteristic parameters for the laser pulse width from several to 10 femtosecond picosecond pulse repetition frequency, from single pulse to 100MHz, laser wavelength from UV to ir.

After nearly 30 years of research and development, ultra fast laser non hot and cold processing attributes began to be loved. It is suitable for the machining of high precision and complex shape devices which can not be realized by other processing methods. Ultrafast laser micromachining of the main principle is the use of ultrafast laser pulse focusing "focus" and the material nonlinear interaction, the minimum can induce photochemical changes in sub wavelength to the nanometer scale and the local material properties changed by computer pattern generation and "focus" scanning, multi beam interference and self coherence etc. the way, micro structure, micro device fabrication.

The advantages of ultrafast laser micromachining are summarized as follows:

The suitable materials of broad spectrum, especially difficult processing materials.The photon energy of ultrafast laser beam is highly concentrated in time, after focusing power density can reach a very high value, the use of ordinary commercial ultrafast laser can induce an easy job to do almost any material molecular bonds break and ionization state, and physical property variation caused by the irreversible phase transition provides a physical basis for ultrafast laser material processing.Due to the high strength, ultrafast laser processing has a broad spectrum of materials, including diamond, sapphire, glass, semiconductors, metals, ceramics and polymers and other materials.

The processing precision is high, suitable for the preparation of complex 3D structures.Due to the nonlinear absorption processes such as multiphoton absorption cross section is very small, light excitation in the focal region of bounded minimum detention area; in addition, due to the excitation of ultrafast, avoid thermal relaxation, so ultrafast become a quasi adiabatic process, and light as an electromagnetic wave is different from the real particle wave, can penetrate the transparent material, processed from the inside.These guarantee ultrafast laser processing with high three-dimensional processing resolution, even exceeding the optical diffraction limit, to nanometer scale.

The non mask technique, suitable for non planar processing.Ultra fast laser micro machining is controlled by computer program, and is scanned in accordance with the drawings of the structure to be processed.The pattern definition does not require mask assistance, and is a non mask micro nanofabrication technique.Without the mask, the laser focus can be scanned by the optical surface, and the microstructure is fabricated on the non flat surface substrate.

At present, ultrafast laser micro machining has been widely used in consumer electronics, Bio Medical, aerospace, information technology, new energy, new materials and other industries.The processing techniques include drilling, scribing, slotting, surface texturing, surface modification, internal modification, welding, finishing, cleaning, etc..Around these ultrafast laser processing technology, industry chain related enterprises and research institutes are developing more stable performance, low cost and ultrafast laser device, beam shaping space transmission technology, combined with the optimal processing technology of material properties and manufacturing technology and intelligent control of.

Market

According to the special study on photonic and laser industry Strategies Unlimited predicts that the global sales laser market in 2019 will reach $12 billion, while the total market of ultrafast laser will exceed $1 billion 400 million, the market growth rate is the ultrafast laser laser market grew two times as fast.The growth rate of femtosecond laser is larger than picosecond laser.The gap between the two is shrinking, which will lead to the use of femtosecond lasers in picosecond laser applications.

Extending from the perspective of industry chain, the laser industry should look like this, the laser output value of 1 billion yuan, 5 billion yuan output value of the laser processing system to the application to provoke the output value of 50 billion yuan, so that by 2020 up to the size of the ultrafast laser industry chain to more than $70 billion of the scale.As early as 2010, the United States Raydiance company (acquired by Coherent in 2015) President Scott Davidson predicted that in 10 years, ultrafast laser technology will have more than $100 billion market, and now his prediction is becoming a reality.

Domestic and foreign companies engaged in ultrafast laser device manufacturing and ultrafast laser micro processing technology have sprung up to seize the emerging market of ultrafast laser micro processing.Although there are a number of companies developing femtosecond laser devices both at home and abroad, Tom Hausken, chief analyst at Strategies Unlimited, thinks"...More value, that is, significant revenues and profits, comes not from lasers, but from systems built around lasers.Therefore, there are many opportunities here......".

At present, around the ultrafast laser industry domestic and foreign mergers and acquisitions after another, the laser and optoelectronics industry giants layout, the ultrafast laser industry chain enterprises implementing mergers and acquisitions in recent five years, nearly twenty mergers and acquisitions have been implemented, you Changba me play, the next few years, people will see more mergers and acquisitions.

Although it has infinite bright future for the development of ultrafast laser micromachining, but should be aware that the current mature ultrafast laser applications market is very limited, with a large number of companies and into the pursuit of capital, will cause the early industrial overheating will also usher in the bottleneck of industrial development and even short-term slump.But in the near future, with the development of more applications, a broader market will emerge, and ultrafast laser micro machining will flourish for a long time.
