摘　　要：采用氙灯抽运自倍频晶体Nd3 +∶Ca4GdO(BO3 ) 3 (简称Nd∶GdCOB) ,Cr4+∶YAG被动调Q ,实现了Nd∶GdCOB晶体被动调Q激光运转 ,测量了饱和吸收体Cr4+∶YAG不同小信号透过率下绿激光单脉冲的输出能量、脉冲宽度、重复率 ,给出了描述Nd∶GdCOB晶体调Q工作原理的耦合波方程组 ,数值求解了该方程组 。Nd 3+∶Ca 4GdO(BO 3) 3, known as Nd∶GdCOB, is a new self-frequency doubling laser crystal. Using Cr 4+∶YAG as passive Q-switch, the Q-switched laser running at 0.53 μm with the Nd∶GdCOB crystal is realized. The pulse width, single pulse energy and repetition rate under different small-signal transmission of Cr 4+∶YAG and different pump conditions are measured and the numerical solutions of the coupling wave rate equations agree with the experimental results.
