摘要

基础知识学习与知识综合应用的脱节一直困扰着大学基础物理教学。由于空气自聚焦效应和等离子体散焦效应共同导致的飞秒激光成丝现象是强激光非线性光学研究的热点话题。为了培养学生的对光学、原子物理学、电子学、数值分析和机械制图等基础知识的综合应用能力，和学生一起设计了创新演示实验去探究飞秒激光成丝过程。采用荧光测量和声音测量两种方法对比研究光丝在不同位置处的演化情况。

Abstract:

The gap between fundamental knowledge learning and their comprehensive application is always achallenge in the undergraduate teaching of basic physics.The phenomenon of femtosecond laser filamentationcaused by the combination of air self-focusing and plasma defocusing effects is a hot topic in the study of strongaser nonlinear optics.n order to cultivate students’ability of practical and comprehensive application of basic

Key words: innovative demonstration experiment femtosecond laser filamentation fluorescence measurement acoustic measurement
