Abstract By using a Q-switched YAG Laser and a optical path delay set-up, we study the process in whith a laser induces breakdown to produce plasma in air, and obtain time-resolved Mach-Zehnder interferograms and optical shadowgrams of the initial stage of the plasma and the expansion wave produced in the process for the first time
