Advantages of Fiber Laser

Fiber laser has the characteristics of small volume, low energy consumption, long life, high stability, maintenance free, multi band, green environmental protection, etc. it has won the affirmation of many laser
fiber laser source
industry insiders for its superior beam quality, stable performance and ultra-high photoelectric conversion efficiency.
 
Fiber laser sets a new standard for laser processing industry with its ultra-high reliability, excellent beam quality and low operating cost.

It has long gain medium, high coupling efficiency, good heat dissipation, simple and compact structure, flexible and convenient use, good output laser beam quality and wide output wavelength range.

1. High power fiber lasers are all double clad fibers. When the pump light hits the cladding, the energy is absorbed and then partially converted into laser. Therefore, the cladding material and structure have a

great influence on the fiber lasers. At present, various shapes of fibers have been developed in various countries, including round, D-shaped, rectangular, unstable cavity, quincunx, square, plane thread, etc.

 
2. Without thermoelectric cooler, this kind of high-power wide area multimode diode can work at very high temperature with simple air cooling and low cost.

 
3. The active cladding fiber in the high power fiber laser is doped with ER / Yb rare earth elements and has a wide and flat optical absorption region. Therefore, the pump diode does not need any type of

wavelength stabilization device.

 
4. High efficiency. The pump light passes through the single-mode fiber core many times, so its utilization is high.

 
5. High reliability. The side pump is directly welded and coupled with branched fiber. On the one hand, there is no need for any optical elements; on the other hand, it can avoid damaging the end face of the

fiber; on the other hand, it is easy to improve the injection efficiency of the pump source. Novel centipede type side pump mode: there are many fiber branches on both sides of the fiber, which are directly fused

with the LD tail fiber, a single pump from different points can avoid the nonlinear effect and mode deterioration caused by a single point of intense laser.

 
Several high power single LD transistors are used instead of LD integrated array as pump source, A mode for improving the light source,

 
Second, it is easy for the heat dissipation of the pump source to improve the service life,

Third, it is conducive to maintenance and replacement.

 
Using LD with wide light-emitting surface as pump source can greatly reduce the light power density of LD light-emitting point and improve its service life, which can generally reach 100,000 hours.
