| 摘 要： | 为分析同向泵浦喇曼光纤放大器中各参量对增益的影响，根据同向耦合波方程导出了放大器输出端信号光的解析解，并给出了放大器增益的表达式。在参量取典型值的条件下，分析了光纤长度、初始信号光功率、初始泵浦光功率、光纤有效面积、拉曼增益系数等参量对放大器增益的影响，所得部分结果与文献的实验结果一致。根据各个参量对放大器增益的不同影响，可以优化放大器的增益特性，从而提高放大器的增益，进而提高其放大性能。

| Abstract: | In order to analyze the effects of the parameters of the forward-pumped Raman fibre amplifier on the gain, this paper presents the analytical solution to the output signal and the theoretical expression of the gain by solving the forward-pumped coupling equations of the amplifier. Then, the effects of the fibre length, the initial signal power, the initial pump power, the effective fibre area and the Raman gain coefficient on the gain of the amplifier are investigated in the condition that the parameters are all of their typical values. Some of the findings are consis tent with the experimental results in the literature. It is finally concluded that the gain characteristics of the amplitier can be optimized based on the different effects of the parameters, thus improving the gain as well as amplifying the performance of the amplifier. |
