为了分析同向抽运与反向抽运光纤拉曼放大器的最大拉曼增益,基于耦合微分方程,采用理论推导的方法,根据不同抽运结构下信号光放大的不同实际情况定义并推导出同向抽运光纤拉曼放大器和反向抽运光纤拉曼放大器的最大拉曼增益公式。然后,详细分析了各个参数对两种抽运方式下光纤拉曼放大器的最大拉曼增益的影响。对两种抽运方式下相同参数引起的最大拉曼增益进行了比较。结果表明,同样的参数对同向抽运与反向抽运光纤拉曼放大器最大拉曼增益的影响有相同的地方,也有不同的地方。最后,将最大拉曼增益和常用的开关增益进行了比较。对光纤拉曼放大器的实验、成本估计和器件效率等研究有重要参考意义。
In order to analyze the maximum Raman gain of the fiber laser amplifier in the same direction and in the opposite direction, based on the coupled differential equation, the theoretical derivation method is used to define and derive the maximum Raman gain of the fiber Raman amplifier according to the different actual conditions of signal light amplification under different pumping structures Maximum Raman Gain Formula for Pumped Raman Amplifier and Reverse Pumped Raman Amplifier. Then, the influence of each parameter on the maximum Raman gain of the fiber Raman amplifier under two pumping modes is analyzed in detail. The maximum Raman gain caused by the same parameters under the two pump modes is compared. The results show that the same parameters have the same influence on the maximum Raman gain of the pump-back and back-pumped fiber Raman amplifiers, and also have different places. Finally, the maximum Raman gain and the common switching gain are compared. The experiment of fiber Raman amplifier, cost estimation and device efficiency have important reference significance.
