摘要
通过对速率方程的数值求解,得到二极管泵浦调Q固体激光器的性能参数,即由激光器的结构参数和泵浦参数,求解出激光器的输出参数。然后将其求解得到的输出与设计要求的激光器输出进行比较,由此对输入的结构参数和泵浦参数进行反复调整,直至最终输出参数满足设计要求的误差。根据该方法设计了3款激光器,实验验证了该算法的可行性。
Through the numerical solution of the rate equations of a four-level laser and the modification of laser inputs combined with feedback,optimization and design of the diode-pumped Q-switched solid-state laser is proved.First,the laser outputs are obtained by solving the rate equation with the preset laser structure parameters and pump parameters,and then the outputs are compared with the design requirements in order to modify the preset laser structure parameters and pump parameters.The modification cycle will not stop until the laser outputs meet our needs.Three types of Q-switched lasers are designed according to the algorithm in the experiments,and the results show a good agreement with the calculation.
