摘　　要：根据四能级非线性速率方程 ,对连续LD泵浦Nd∶YVO4 /Cr4 + ∶YAG/KTP腔内倍频被动调Q绿光激光器的输出特性进行了数值模拟。理论分析与实验相一致 ,所得结果对该类器件参数优化具有参考价值。In order to study the gain medium, Nd∶YVO 4,pumped continuously by LD, Cr 4+ ∶YAG saturable absorbers and intro cavity doubling KTP crystal are used in a passive Q switched green laser. Based on the rate equation of the fore level system and numerical simulation, the relationship of the system parameters and the characteristics of the laser beam are analyzed.The theoretical results conform to the experimental results.It is useful to optimize and select the parameters of such systems.
