摘　　要：本文提出一种测量受激拉曼散射阈值光强的方法,利用光学多道分析仪的递增延迟时间功能控制调Q开关,改变输出的激光光强以达到测量阈值光强的目的。这种方法适用于对激光光强表现出阈值特性的物理量的测量。A method of measuring Stimulated Raman Scattering thresholdintensity is presented. In order to measure threshold power,we use theincremental delay function of optical multichannel analyzer to vary laseroutput by the way of controlling laser Q switch. This method is also suit-able for measuring other physical quantities which have threshold propertiesto laser
