摘要
从速率方程出发,对波长为980nm的激光泵浦掺Yb3+光纤激光器进行数值模拟,全面分析激光器阈值功率、输出激光功率、增益等重要参数与泵浦功率、光纤长度、腔镜反射率、掺杂浓度等参量之间的关系。采用高浓度掺Yb3+光纤对环形光纤激光器做了初步实验研究,所得结论与实验模拟结果基本一致。
Numerical analysis of a Yb3+-doped fiber laser pumped by 980 nm laser source is presented in this paper. It is studied that the relationships between the important characteristics of the Yb3+ doped fiber laser such as threshold power, output power and gain and laser parameters such as pump power, fiber length, mirror reflectivity and Yb3+ concentration. A highly-doped Yb3+ fiber ring laser with short cavity is presented. Numerical results are coincident with the experiment phenomenon.
