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,所得的理论结果与实验值相符合.
Abstract
Nd3+∶Ca4GdO(BO3)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.
