摘　　要：用数值积分法计算阶跃Q开关激光器输出光脉冲波形,并由计算得出的数据与模拟实验结果基本相吻.最后分析出四能级系统激光器中存在严重的差瓶颈效应,此导致了图形中的上升阶段初始时间内的差异,和下降阶段末端时间内的差异.The output pulse waveform of the step Q switched laser is calculated with the method of numerical integration, and the data calculated is coincided with the results of simulating experiment. It is finally analyzed that four-level system laser has serious differential bottleneck effect, which causes the differences both in the initial time of rising phase and in the final time of declining phase of waveform.
