Fiber laser is gradually replacing the traditional laser in laser marking, laser welding, laser cutting, and other areas of leading positions. In the field of marking, fiber laser has high beam quality and positioning accuracy.

1.Application of fiber laser marking machine in the industry

Industrial production requires high reliability, small volume, quiet, easy to operate. Fiber laser is widely concerned because of its compact layout, high light conversion, short preheating time, little influence by the situation factors, maintenance-free and easy coupling with optical fiber or optical lens.

Currently, fiber laser is gradually replacing the traditional laser in laser marking, laser welding, laser cutting, and other areas of leading positions. In the field of marking, due to the high beam quality and positioning accuracy of optical fiber laser, the optical fiber marking system is replacing the Nd: YAG pulse laser marking system which is not subject to high carbon dioxide laser and xenon lamp pumping; in the market of Taixi and Japan, this kind of replacement is held in an upright range, and in Japan alone, the monthly demand exceeds 100 sets. As the largest industrial manufacturer in the world, China has a huge demand for an optical fiber laser marking machine, which is expected to exceed the demand of 2000 sets every year. In the field of laser welding and cutting, with the success of the development of the fiber laser of the upper kilowatt or even tens of thousands of watts, the fiber laser has also been applied. Previously, IPG reported that BMW purchased its high-power fiber laser for door welding production line.

2.Application of fiber laser marking in sensor

Compared with other light sources, fiber laser has many advantages when used as a sensing light source. First of all, the fiber laser has high availability, tunability, good stability, compact, lightweight, convenient maintenance, and good beam quality. Secondly, the fiber laser can be well coupled with the fiber, fully compatible with the existing fiber devices, and can carry out all fiber testing.

Fiber sensing based on tunable narrow-linewidth fiber laser is one of the most popular applications in this field. The spectral linewidth of the sample fiber laser is very narrow, it has a super long correlation length, and it can modulate the frequency quickly. By applying the narrow linewidth fiber laser to the diffuse sensing system, the ultra-long interval and ultra-high precision fiber sensing can be realized. In the United States and Europe, this sensing technology based on tunable narrow-linewidth fiber laser is widely used in many fields, such as the monitoring of peaceful and tense methods in the territory, the monitoring of kerosene / natural gas pipelines, and the detection of underwater sonar.

3. Application of fiber laser marking in communication

Compared with the general laser system, fiber laser has obvious advantages in a compact layout, heat dissipation, beam quality, volume, and compatibility with the existing system, and has been widely used in the field of communication.

The mode-locked fiber laser with rare-earth-doped fiber as a gain medium can generate ultrashort optical pulses with high repetition rate and pulse width of picosecond or femtosecond, and its lasing wavelength falls on the optimal window of 1.55 μ M band of optical fiber communication, which is the ideal light source for a high-speed optical communication system in the future. Now, 10 GHz and 40 GHz repetition rate mode-locked fiber lasers have been successfully developed. Once this kind of communication network is laid, the demand for this sample laser will be huge.

4. Application of fiber laser marking in therapy

Nowadays, most of the lasers used in the clinic are argon-ion laser, carbon dioxide laser, and YAG laser, but usually, their beam quality is not high, they have very large volume, they need huge water cooling system, and they are very poor in installation and maintenance, which is just what fiber laser can supplement. Since water molecules have a peak at 2 μm, the use of 2 μm fiber laser as a surgical tool can achieve rapid hemostasis and eliminate the crushing of human body structure.
