连续腔内倍频拉曼激光器的归一化理论解析

腔内倍频拉曼激光器是获得黄光激光光源的重要途径,目前尚未有直接的表达式描述连续腔内倍频激光器的功率输出对抽运和激光器参数的赖关系。以速率方程为基础,对腔内倍频连续拉曼激光器的理论模型进行归一化处理,得到平面波近似下连续腔内倍频拉曼激光器的归一化速率方程组。对此方程组进行求解,得到描述激光器输出的表达式各变量以及参量与输出变量之间的归一化表达式,根据表达式获得了描述激光器运行的理论曲线。

Normalized theoretical analysis of continuous-wave intracavity frequency-doubled Raman laser

CW intracavity frequency-doubled Raman laser has become an important approach of CW yellow laser, and the formula which directly described the variation of the laser output with input pump power and laser parameter was not given. A theoretical model of continuous-wave intracavity frequency-doubled Raman laser based on normalized rate equations with plane-wave approximation was built. By solving these normalized rate equations, the expression which described the variation of normalized yellow laser output with the normalized input and normalized laser parameter was obtained, and the theoretical curves which were also obtained. The relations between the normalized output and normalized input as well as normalized parameters was discussed. The model can be used to help the design of the lasers.
