| 摘 要： | 建立了一种考虑受激布里渊散射(SBS)效应和输出光纤影响的光纤放大器模型,该模型能有效描述低频脉冲的放大过程。数值仿真表明,通过优化设计掺杂光纤长度,缩短输出光纤长度,增大输入脉冲峰值功率等操作可以有效抑制光纤放大器中的受激布里渊散射。本文的结果可为单频放大系统的设计提供理论依据。

| Abstract: | Considering the influence of stimulated Brillouin scattering (SBS) and the output fiber,a fiber amplifier model is established,and it can effectively describe the amplification of low-frequency pulse. The simulation results show that SBS in fiber amplifier can be effectively suppressed through optimizing length of the doped fiber,cutting down length of the output fiber and increasing peak power of input pulse. The research results can be applied to the design of the single-frequency amplification system. |
