摘要
介绍了超短激光脉冲技术的基本原理和产生过程,分析了超短脉冲的压缩技术以及近年来比较常用的几种测量技术直接测量法和间接测量法,重点研究了基于二次谐波的频率分辨光开关法(FROG)的脉冲测量法,以及这种测量方法的优缺点,并与自参考光谱相位相干电场重建法(缩写为SPIDER)进行了比较,分析了两种测量法各自的优缺点。
We analyze the basic principle and generation, several methods of measurement of ultrashort laser pulse technology In this paper. Studied based on FROG, as well as the advantages and disadvantages of this method of measurement, and comparison with SPIDER. Analyzed the advantages and disadvantages of two measurements.
