| 摘 要： | 将打靶法和龙格库塔法两种数值计算方法相结合，对反向抽运光纤喇曼放大器中信号光和抽运光相互作用的耦合微分方程进行数值求解.在分别选取不同参量且取不同值的条件下，详细分析了光纤长度、初始信号光功率、初始抽运光功率、光纤有效面积、喇曼增益系数及光纤对信号光与抽运光的损耗等参量对增益的影响，最后提出了有效提高增益的方法.

| Abstract: | By combining shooting method with Runge-Kutta method for solving differential coupling equations of backward-pumped fiber Raman amplifier (FRA),the effects of fiber length,initial signal power,initial pump power,fiber efficient area,Raman gain coefficient,and fiber loss of signal and pump on gain of FRA have been detailedly investigated. Finally,several ways are suggested to improve the gain of backward-pumped FRA. Accurate and reasonable results have been gotten,and are helpful to the study of FRA. |
