四能级单模光纤激光器的理论分析

Theoretical Analysis of Four-Level Single Mode Fiber Laser

本文利用四能级速率方程,推导出掺杂单模光纤激光器中输出功率与輸入泵浦功率之间的关系及阈值泵浦功率,并对掺钕单模光纤进行了计算。理论结果与实验结果相当吻合。

The relation between the output power and the input pump power and then the threshold pump power are analyzed in terms of the four-level rate equations. The. threshold pump power and the slope efficiency of Nd-doped single mode fiber are calculated. The theoretical results are in good agreement with the experimental results.
