摘　　要：介绍一种采用小孔光阑穿透来测量激光脉冲方向性的时间演化过程方法，并对放大倍率为Ｍ＝１０（振荡器Ｍ＝３０）的注入锁定铜激光器输出光脉冲方向性时间分辨过程进行了测量。结果表明：在激光脉冲的形成过程中，输出光方向性越来越好，相应发散角由～１．０ｍｒａｄ连续地减小到０．１２ｍｒａｄ。最后对实验结果进行了讨论。In this paper, a method of time - resolved divergence measurement using an aperture is reported. With this method, we measured the evolution of the beam divergence of output pulse from an injection locking copper vaper laser (CVL) of magnification.M = 10(M = 30 for oscillator). The experimental results show that the beam divergence becomes smaller and smaller reducing from ￣ 1. 0 mrad to 0. 12 mrad. The experimental results are analysed.
