Influence of Light Leakage from Q-Switched Laser on Laser-Induced Shock Wave

Abstract:

Experiments were performed to study the influence of light leakage from Q-switched laser on laser-induced shock wave. Through changing the voltage applied on the Q switch crystal and the delay time between opening Q switch and triggering laser pumping source, different amount of light leakage can be obtained. It is ascertained that longer-pulse light leakage from Q-switched laser is responsible for the second weaker pressure signal appearing on the tested pressure waveform. The results show that the leakage energy not only has not beneficial effects on laser shock processing, but also will weaken the main pressure wave.
