| 摘 要： | 基于速率方程的离散算法,对连续和脉冲泵浦下的双包层Er3 /Yb3 共掺光纤放大器ASE动态特性进行了研究,对ASE随时间呈现不同变化的原因进行了分析。结果表明:连续光泵浦下,双包层Er3 /Yb3 共掺光纤放大器ASE达到稳态的时间和输出功率的大小依赖于泵浦功率,ASE输出功率的增加与Er3 上能级粒子数的减少相对应;脉冲光泵浦下,光纤长度对正向ASE输出功率的饱和存在显著的影响,但不影响反向ASE输出功率的饱和。

| Abstract: | Based on discrete algorithm of propagation-rate equation,the ASE dynamic behavior of Er~(3 )/Yb~(3 ) co-doped double-clad fiber amplifier under both continuous and pulse pumping is studied.The reason for different change of the ASE output power with time is analyzed as well.The results show that the time and output power value of ASE reaching steady state under continuous pumping depend on the pump power,and the increase of ASE output power corresponds to the decrease of the inverted population of Er~(3 ).This study also shows that the length of the fiber under pulse pumping affects significantly the saturation of the forward ASE output power,but does not affect that of the backward ASE output power. |
