New Product 976nm 420W Pump Fiber Coupled Laser Diode

2021-08-10
In the industrial laser application, people usually use 915nm pumping in the past, but with the rapid development of fiber lasers, the market demand for higher power has become more and more prominent, and competition is becoming increasingly fierce. The 915nm wavelength has lower absorption efficient which brought double obstacles in cost and technical, limiting the development of high-power and low-cost fiber coupled laser modules.

Because of the higher absorption coefficient for 976nm wavelength. Under the same pump power injection, compared with the 915nm, when the 976nm pumping scheme is adopted, the output power of the fiber laser will be 13% higher, and the length of the gain fiber required for 976nm waveband pumping is shorter, which directly reduces the material cost, while also effectively reducing the nonlinear effect, the loss of optical efficiency, and the difficulty of thermal management.

In addition to the fanatical pursuit of high power and high brightness, the market is in urgent need for cost-effective pump modules. The price war in the market competition is becoming increasingly fierce. The 420W 976nm pump source is newly launched which increase the power and reduce the cost.
