摘　　要：飞秒激光是目前人类在实验室条件下所能获得的脉冲最短的激光,具有广泛的应用空间。本文介绍了超短激光脉冲宽度技术的基本原理,分析了近年来超短脉冲宽度的测量方法,包括直接测量法和间接测量技术。在此基础上,搭建了飞秒激光自相关宽度测量系统,并在60fs~1ps范围内进行了脉冲自相关宽度测试。Femtosecond laser is the shortest pulse laser at present that can be obtained under laboratory conditions.This paper introduces the basic principle of ultrashort laser pulse width technology,and analyzes the measurement methods of ultrashort pulse width in recent years,including direct and indirect measurement technology.On the basis,a femtosecond laser autocorrelation width measurement system is built,and the autocorrelation width is measured in the range of 60fs~1ps.
