Raman放大器中抽运与信号脉冲的相互作用

Interaction between pump and signal pulse for Raman amplifier

光纤Raman放大的抽运光采用窄脉冲形式时,需对连续波理论进行修正。基于光纤Raman放大的振幅耦合方程,分析色散、走离、非线性、SRS等对Raman放大带来的影响。

CW theory should be modified when fiber Raman amplifier is pumped by narrow pulses. Based on the amplitude coupled equations desc.ribing fiber Raman amplification, the afections for dispersive, nonlinear, walk-off,and SRS effects on Raman amplification arc analyzed.
