摘要

模拟了可饱和吸收材料长度对由两个波长( 和 )而非单波长产生的双被动 Q 开关脉冲特性的影响。 模拟中使用了 Rung-Kutta-Fahelberg 方法对我们之前的速率方程模型进行数值求解。Nd+3 :YAG 用作活性介质,Cr+4:YAG 用作可饱和吸收材料。结果表明,Nd+3:YAG 双被动 Q 开关产生或释放的时间较早(提前),并且具有持续时间短、高能量和高功率的特点,且随着θ 值的增大而增大。 在θ 值约为 58ns、60ns 时,Nd+3:YAG 的被动 Q 开关分别释放;在θ 值约为 34ns、36ns 时,Nd+3:YAG 的被动 Q 开关分别释放。脉冲的持续时间在Ⅴ阶段分别约为 16.8ns、14.6ns,在Ⅳ阶段分别约为 10.8ns、9.2ns。

Effect of Saturable Absorber Length on Characteristics of Dual Laser Pulses of Passive Q-Switched
The effect of saturable absorber material length on the characteristics of the dual passive Q-switching pulses generated from two wavelengths (  and ) instead of single wavelength was simulated.  Numerical solution of our previous rate equations model using Rung-Kutta-Fahelberg method has been utilized in simulation. Nd+3 :YAG using as an active medium, and Cr+4:YAG as a saturable absorber material. The results showed that  the Nd+3:YAG dual passive Q-switching generated or released at an advanced(earlier) time and characterized by short duration times, high energy and high power with the increasing in the value of . The passive Q-switching for ,  are released respectively at time 58ns, 60 ns approximately at , while released at time 34 ns, 36 ns respectively approximately at . The duration time of   ,  pulses approximate to 16.8ns, 14.6 ns respectively at , while approximate to 10.8 ns ,9.2 ns respectively  at .
