通过数值模拟研究了双端泵浦的高功率掺镱双包层光纤激光器的输出特性。
The output characteristics of two-end-pumped Yb 3 -doped double clad fiber lasers are studied by numerical simulation.
当光纤长度较短时，在输出端放置反射镜使泵浦光高反射，可以提高输出功率和效率。
For short fiber, the output laser power and slope efficiency can be improved when a reflective mirror is set at output end to reflect the pump light.
在一个实施例中，控制器228的输出端232被光耦合到拉曼光泵浦源208的控制输入端236，如结合图1所描述的那样。
In one embodiment, the output 232 'of the controller 228 is optically coupled to a control input 236 of the Raman optical pump source 208 as described in connection with Fig. 1.
