Analysis on the Application of Fiber Laser in Different Industries

  Fiber lasers are gradually replacing the traditional lasers in laser marking, laser welding, laser cutting and other areas of the dominant position. Easy to network for everyone to explain the advantages of fiber lasers in various fields of application.

  Fiber laser marking machine in the industrial application

  Industrial production requirements Laser high reliability, small size, quiet, easy to manipulate. Fiber lasers are favored by people because of their compact layout, high light conversion, short warm-up time, small influence on conditions, maintenance-free and easy coupling with optical fiber or optical system. Now, fiber lasers are gradually replacing traditional lasers in laser marking, laser welding, laser cutting and other areas of the dominant position.
  In the field of marking, due to the high beam quality and positioning accuracy of fiber laser, fiber marking system is replacing the Nd: YAG pulsed laser marking system which is not subject to the high carbon dioxide laser and xenon pumping. In Taixi and Japan, this substitution is taking place on a large scale. In Japan alone, the monthly demand is above 100 units. According to IPG reports, after Germany's BMW Motor Company acquired their high-power fiber laser used in the welding production line.
  As the largest manufacturing country in the world, China has a huge demand for fiber laser marking machines. It is predicted that there will be more than 2,000 demand each year. In the field of laser welding and cutting, with the successful development of thousands of watts and tens of thousands of watt fiber lasers, fiber lasers have also been applied.

  Application of Fiber Laser in Sensing

  Fiber lasers have many advantages as sensing light sources over other light sources. First of all, fiber lasers have excellent utilization, tunability, robustness, compactness, light weight, easy maintenance and good beam quality. Second, fiber lasers are well-coupled with fiber optics and are fully compatible with existing fiber optic components for full fiber testing.
  Fiber sensing based on tunable narrow linewidth fiber lasers is now one of the hot applications in this area. The fiber laser has a very narrow spectral linewidth, long stem length, and fast modulation of the frequency. The narrow linewidth fiber laser applied to diffuse sensing system, can achieve ultra-long interval, ultra-high precision optical fiber sensing. Sensing techniques based on tunable narrow linewidth fiber lasers are widely used throughout the United States and Europe. China expects the annual demand for such an example fiber laser is also more than 100 units.

  Application of Fiber Laser in Communication

  Compared with other types of lasers, fiber lasers have obvious advantages in terms of layout compactness, heat dissipation, beam quality, size and compatibility with existing systems, and are widely used in the field of communications.
  Mode-locked fiber lasers doped with rare earth fibers as gain medium can breed ultra-short optical pulses with high repetition rate and picosecond or femtosecond pulse widths, and their lasing wavelengths fall within the optimum window of optical fiber communication of 1.55 μm Band, is the future high-speed optical communications system as the light source. Now, 10GHz and 40 GHz repetition rate mode-locked fiber laser has been successfully developed. Once this communications network is deployed, the need for this example laser will be enormous.

  Application of fiber laser in therapy

  Today, most clinically used lasers are argon ion lasers, carbon dioxide lasers and YAG lasers, but usually they have poor beam quality, a very large volume, a huge water cooling system, and very difficult to set up and maintain, Fiber laser can be added. Since the water molecules have an absorption peak at 2 μm, the use of a 2 μm fiber laser as a surgical tool enables rapid hemostasis and avoids the damage to the human body caused by the operation.
