摘　　要：为了研究多阶级联喇曼光纤激光器的结构参量对输出特性的影响,利用数值模拟的方法对表征多阶级联喇曼光纤激光器的非线性耦合方程组进行了求解,在此基础上,对6阶掺锗级联喇曼光纤激光器进行模拟分析,得到了光纤长度、输出镜反射率、抽运功率等因素与6阶级联喇曼光纤激光器结构参量的关系。结果表明,在抽运功率不变时,光纤长度取300m左右,输出镜反射率取10%左右,阈值功率比较小,可以获得最大输出功率。In order to study the dependence of output characteristics on the parameter of multi-order cascaded Raman fiber lasers,the nonlinear coupled equations, describing modeling of multi-order cascaded Raman fiber lasers, were solved. Based on numerical simulation, the effect of fiber length, reflectivity of output coupler and pump power on the output characteristics of a 6- order cascaded Raman fiber laser was obtained. The results showed that the Raman fiber lasers had lower threshold power and could obtain the maximum output power when the fiber length was about 300m, and the reflectivity of the output mirror was about 10%.
