| 摘 要： | 根据掺铒光纤激光器的速率方程，对环形腔光纤激光器的输出特性进行了理论分析，得到了光纤激光器在稳态条件下阈值抽运功率、激光输出功率和斜率效率的解析表达式。利用数值模拟结果对光纤激光器的这些基本特性参量进行了分析和讨论，为光纤环形激光器的优化设计提供了依据。并进行了980nm抽运的掺铒光纤激光器的实验，实验证明理论分析得到的基本特性是合理的。

| Abstract: | Based} on the rate equations applicable to the erbium|doped fiber laser, a continuous erbium|doped fiber laser of ring cavity has been studied, and analytical expressions on threshold pump power, laser output power and slope efficiency under stationary condition have been derived. Variations of these basic parameters with the length of erbium|doped fiber have been analyzed by the analytic expressions and demonstrated by simulation, which will be help full to the optimization of designing a practical erbium|doped fiber ring laser. The experimental study on erbium|doped fiber laser pumped by 980 nm source has shown that the output characteristics were in good agreement with the theoretical calculations. |
