FP Light Source

Due to the fiber laser pumped at the 976nm, the gain fiber has a higher absorption coefficient for the pump light. Under the same pump power injection, compared with the 915nm pump, the 976nm pumping scheme is adopted. The output power of the fiber laser It will be 13% higher, and the gain fiber length required for 976nm wave pumping needs 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.
