从准三能级系统的速率方程出发，推导出了二极管（ＬＤ）端泵浦连续工作端面泵浦固体激光器的速率方程，提出了计算连续ＬＤ端面泵浦激光器输出功率的方法，并表示成激活介质长度和透过率的函数，由此得到在泵浦功率一定情况时的优化设计步骤。数值计算结果与我们的实验结果和文献［３］，［４］的实验数据符合甚好。
Based on the rate equation of quasi-three-level system, the rate equation of continuous working end-pumped solid-state laser with end-pumped diode (LD) was deduced and the method to calculate the output power of continuous LD end-pumped laser was proposed and expressed as active Media length and transmittance as a function of the pump power obtained under certain circumstances, the optimal design steps. The numerical results are in good agreement with our experimental results and the experimental data in [3] and [4].
