摘　　要：本文描述了一种能够快速准确地测量脉冲染料激光束直径的方法,该方法是以步进电机驱动针孔扫描,Boxcar—Computer信号处理系统做高斯拟合,精度优于5％。This paper described a method that can quickly and accurately measure the diameter of dye laser beam pumped by the frequency doubled laser of Nd: YAG using a set of step motorprecision screw drived pinhole scanning and Boxcar - computer signal processing system. The uncertainty of the measurements is less than ±5%.
