Abstract

By using optical interference and shadowing methods and an optical path delay set-up, the initial process of laser-induced self-focusing in H2 is studied on one Q-switched YAG laser and a series of time-resolved Mach-Zehnder interferograms and shadows are obtained. Some phenomena during the self-focusing are observed and explained. The theoretical model of moving foci is demonstrated by the experiments discussed in this paper.
