摘　　要：根据被动调Q速率方程模拟了Cr4+∶YAG晶体被动调Q的输出特性,给出了输出脉冲宽度和能量。介绍了一种采用一体化设计的激光器,体积较小,并可稳定工作于1~40Hz,输出能量大于11mJ,脉冲宽度5.2ns,发光时刻稳定性小于2.5μs,环境温度适应性:-40^+55℃。On the basis of passivity Q-switch rate equations, the passivity Q-switch output characteristics of Cr4＋：YAG is simulated,and output pulse width and its energy are presented. The laser is designed integrative and has small eubage. The laser works at the repetition rate of 1 - 40 Hz. The output energy is more than 11 m J, and the pulse width is 5.2 ns. The jitter of laser is less than 2.5μs. The laser has passed the temperature test of -40 ～ ＋55℃.
