An empirical experimental investigation on the effect of an external electric field on the behaviour of laser-induced cavitation bubbles.

This study is an attempt to empirically investigate the behaviour of laser-induced cavitation bubbles under the influence of an external electric field. As such two targets (copper and iridium) were subjected to a high-power Nd:YAG laser beam while being submerged in a liquid. Three different liquids were chosen for this purpose acetone, ethanol, and distilled de-ionized water.
