Abstract

By using a Q-switched YAG laser and an optical path delay set-up, we study the process in which as laser induces breakdown to produce plasma in air. We obtained time-resolved Mach- Zehnder interferograms and optical shadowgrams of the initial stage of the plasma, and shock waves produced in the process are obtained.
