| 摘 要： | 由稳态条件下描述光纤中受激拉曼散射(SRS)效应的光功率耦合方程出发,采用解析方法对多阶级联拉曼光纤激光器(CRFLs)进行了理论分析。根据拉曼光纤激光器级联阶数的奇偶性分别推导出了多阶级联拉曼光纤激光器的输出功率、光-光转换效率最大时的拉曼光纤长度和输出耦合器反射率。通过忽略反射回谐振腔输入端的剩余抽运光功率,计算了5阶级联拉曼光纤激光器的输出特性和光-光转换效率随光纤长度和输出耦合器反射率的变化。利用已有的5阶级联掺锗拉曼光纤激光器输出特性实验数据与理论分析结果进行了对比。

| Abstract: | Multi-order cascaded Raman fiber lasers(CRFLs) are analyzed by an analytical method from optical power coupling equation under steady states used to describe stimulated Raman scattering(SRS).According to the parity of cascaded number,the output power is deduced,and the optimal length of Raman fiber and reflectivity of output-coupler are also obtained when the maximum pump-to-Stokes conversion efficiency is reached.The output characteristics and conversion efficiency as a function of Raman fiber length and output-coupler reflectivity of a 5th-order Ge-doped CRFL have been calculated with the residual pump power reflected into the input-end of resonant cavity being ignored.The comparison of calculated results and the experimental data for the 5th-order CRFL has been made. |
