| 摘 要： | 本文分析了损耗对线形腔掺镱双包层光纤激光器输出特性的影响。对有损耗的线形腔掺镱双包层光纤激光器输出特性进行了数值分析,(当考虑光纤损耗时)得出了泵浦功率和正反向激光功率在2 0米长光纤处有近2W降低(泵浦功率为2 0W时)的结论。同时,文中给出了有损耗时的输出功率与光纤长度、泵浦功率和后镜反射率R2 的关系曲线。

| Abstract: | In this paper,the affects of loss to output characteristic of Yb 3 -doped doubled-clad fiber lasers are presented by numerical analysis,and the result(than non-loss Yb 3 -doped doubled-clad fiber lasers),a fall of about 2W pump power or forward/reverse power is got at 20m fiber length Meanwhile the relation curves between output power fiber length,pump power and back mirror reflectivity R 2 are given in this paper. |
