Fiber laser applications in different industries
Fiber laser is gradually replacing the traditional laser in laser marking, laser welding, laser cutting and other fields of leadership positions. Otlaser explains the advantages of fiber laser marking in various fields.
Application of fiber laser in communication
Compared with other types of lasers, optical fiber lasers have obvious advantages in compact layout, heat dissipation, beam quality, volume and compatibility with existing systems, and are widely used in the field of communication.
Mode-locked fiber laser with rare earth fiber as gain medium can produce very short optical pulse with high repetition rate, pulse width picosecond or femtosecond, and the laser wavelength falls on the optimal window of optical communication 1.55 microns, which is the ideal light source for high-speed optical communication system in the future. At present, mode-locked fiber lasers with 10GHz and 40ghz repetition frequencies have been successfully developed. Once this communication network is laid out, the need for this example laser will be enormous.
Application of optical fiber laser marking machine in industry
Industrial production requires the laser high reliability, small size, quiet, easy to operate. Optical fiber laser is widely favored for its compact layout, high light conversion compliance, short preheating time, small influence by circumstances, maintenance-free and easy coupling with optical fiber or optical lens to form optical guide system. Now, fiber laser is gradually replacing the traditional laser in laser marking, laser welding, laser cutting and other areas of the leading positions.
In the marking field, fiber laser marking system is replacing Nd: YAG pulsed laser marking system subject to low carbon dioxide laser and xenon lamp pumping because of its high beam quality and positioning accuracy. In taixi and the Japanese market, this kind of substitution is being held on a large scale, in Japan alone, the demand for more than 100 units per month. According to IPG, BMW has previously purchased its high-power fiber laser for the door welding line.
As the world's largest industrial manufacturing country, China has a huge demand for optical fiber laser marking machines, which is expected to exceed 2000 sets annually. In the field of laser welding and cutting, with the development of optical fiber laser of upper kilowatt and even tens of thousands of watts, optical fiber laser has been applied.
Application of fiber laser in treatment
At present, most of the lasers used in clinical practice are argon ion laser, carbon dioxide laser and YAG laser, but usually their beam quality is not high, has a very large volume, requires a huge water-cooling system, and placement and maintenance is very difficult, and these are just fiber laser can supplement. The optical fiber laser can be used to hemostasis quickly and avoid damage to human body structure.
The application of fiber laser in sensing
Compared with other light sources, optical fiber lasers are used as sensing light sources with many advantages. First of all, fiber laser has high utilization rate, tunable, good stability, compact and compact, light weight, easy maintenance and good beam quality and other excellent performance. Secondly, optical fiber laser can be well coupled with optical fiber, fully compatible with existing optical fiber devices, and can be used for all optical fiber testing.
At present, optical fiber sensing based on tunable narrow line-width fiber laser is one of the hot applications in this field. The fiber laser has very narrow spectral line width, ultra-long trunk length, and fast modulation of frequency. By applying the narrow line-width fiber laser to the diffuse distribution sensing system, the ultra-long interval and ultra-high precision fiber optic sensing can be realized. In the United States and Europe, this sensing technique based on tunable narrow-line-width fiber lasers is widely used. It is estimated that the annual demand for this kind of sample fiber laser is more than 100 sets.
