Acoustic signature of stress waves in endothermic surface absorbing targets by Q-switched Nd:YAG pulse laser irradiation

Abstract

We described experimental results on acoustic signature of stress wave induced in a natural rubber or a carbon as a target by irradiation of laboratory scale Nd:YAG pulse laser. We found that the natural rubber was better material than that of carbon as target for generation of impulse stress wave due to impulse coupling of laser and target.© 2012 The Acoustical Society of Japan.
