摘　　要：激光光斑尺寸和激光束腰光斑尺寸是衡量激光器性能的重要参数。本文利用90/10刀口法测量高斯激光光斑尺寸及光束束腰尺寸,给出了两种计算方法,克服了传统方法过程繁杂的缺点,精度高、效率高,操作简单。The spot size and beam waist of laser are important parameters for assessing the performance of lasers. Using the 90/10 knife-edge method, the precision measurement of the spot size and beam waist of laser are discussed, and two calculation methods have been proposed in this paper. The knife-edge method, avoiding the complicated process of traditional measure- ment, is accurate, effective and simple.
