Experimental study of laser-induced cavitation bubbles

Abstract

The focused beam from a Nd:YAG laser (λ=0.532 μm) is used to generate cavitation bubbles in water. Optics of short focal length have been shown to be the most suitable for producing a single bubble in a definite place. Some typical photographs of bubbles obtained are presented. These prove that the laser is a useful tool for the study of simulated cavitation in the laboratory.
