为了对分布式双向抽运光纤拉曼放大器的功率转换效率进行研究，在不同的抽运功率配置条件下，采用打靶法和龙格库塔法相结合的数值算法，由耦合方程出发，详细分析不同物理因素对双向抽运光纤拉曼放大器功率转换效率的影响，包括增益、增益饱和、初始信号光功率以及总的抽运功率。结果表明：信号较小、总的抽运功率较小时，抽运功率配置对双向抽运光纤拉曼放大器效率的影响较小。信号较大、总的抽运功率较大时，抽运功率配置对双向抽运光纤拉曼放大器效率的影响显著；双向抽运 FRA 的功率转换效率随着同向抽运功率占抽运总功率百分比的增加而增加。所得结论有新的进展，对双向抽运光纤拉曼放大器和光纤拉曼放大器功率转换效率的进一步研究有重要参考意义。

In order to analyze power conversion efficiency of distributed bi-directional pumping fibre Raman am﹣plifier (FRA), by combining shooting method with Runge-Kutta method for solving differential coupling equations of bi-directional pumping FRA, the effect of different pump power deployment under different parameter on bi-direction﹣al pumping FRA’s power conversion efficiency have been detailedly investigated, including gain, gain saturation, ini﹣tial signal power and initial pump power. It is found that: pump power deployment has a little influence on bi-direc﹣tional pumping FRA’s power conversion efficiency under small initial signal power and small total pump power, and they increase when initial signal power and total pump power are larger; And, power conversion efficiency will increase when forward pumped FRA’ s pump power is larger. It is helpful to the study of bi-directional pumping FRA and FRA’s power conversion efficiency.
