摘　　要：采用光线追迹的方法 ,建立了一套二极管直接侧面泵浦固体激光器的泵浦光场分布的数值模型 ,运用计算机进行模拟计算 ,分析系统结构参数对泵浦均匀性的影响 ,可为二极管泵浦固体激光器结构设计提供理论指导。实验测试了 3种不同的侧面泵浦方式下激光介质的荧光分布图 ,所得结果与模拟计算结果基本相符 。With ray tracing method,a calculating model of laser diode directly side pumping method is proposed,and the gain distribution characteristics in the active medium side pumped by diode bars are studied.The effects of system parameters change on the homogeneity are analyzed.The fluorescence distributions of the active medium are tested with CCD for three different side pumped construction.The experimental results agree well with the results of the calculation of this model.This model can completely be put into practice.
