摘要
用双通结构理论对采用光纤光栅做腔镜的两级的串级拉曼激光器进行了数值模拟。在此基础上,分析了光纤长度、谐振腔损耗及输出镜反射率等因素对两级掺磷全光纤拉曼激光器的输出功率、阈值、斜率效率等输出特性的影响,并给出了串级拉曼激光器的优化设计参数。
The two cascaded Raman fiber laser using fiber Bragg gratings as cavity mirrors was theoretically simulated and analyzed by use of the double pass configuration. The effects of fiber length, excess loss and output reflectivity on the output characteristics of two cascaded Raman fiber laser, such as output power, slope efficiency, and threshold power were studied on basis of numerical simulations, and the optimized parameters were given.
