Abstract

This paper is concerned with a basic study of vapor bubbles induced by a high power laser beam. It described preliminary studies which should lead to the validation of a laser/ matter interaction code and an hydrodynamic code by optical cavitation experiments. In a first time the experimental arrangements for the generation of a centimeter bubble and for the diagnosis are presented. Visualisations of shock waves and bubbles, pressure and energy mesurements leading to determine a distribution of energy are shown. Then a moderation of the energy depositing and its insertion in a laser/ matter interaction calculation code is presented. A version of the hydrodynamic calculation code PISCES adapted to the study of vapor bubble dynamic and propagation of pressure waves generated during the breakdown and during the collapses is then described (utilization of a multiphase equation of state adapted to the problem).
