摘要
考虑晶体热衍射损耗以及在倍频过程中的非线性腔内损耗的影响,给出了LD泵浦Cr∶YAG被动调Q556nm激光的耦合速率方程,数值求解了该方程组获得输出激光的重复频率,平均输出功率,峰值功率随泵浦功率的变化特性,理论值与实验结果符合较好。
Considering the influence of crystal thermal loss and the intracavity loss of frequency doubling process, the four-lever nonlinear rate equation of passively Q-switched yellow laser is given. The characteristics of pulse-width repetition and output average power versus the pump power are obtained through numerical solution. The theoretical analysis accords with the experimental results excellently.
