Abstract

Under illumination of a solid absorbing target by short laser pulse the acoustic waves are excited both inside the target and in the surrounding air. When the surface of the target is plane the shape of acoustic signal in the air depends on the intensity distribution in the illuminating laser beam. In this report the results of restoration of two-dimensional intensity distribution of pulse laser beam by method of acoustic tomography are presented. As the target a plane metal plate was used. Measurements of acoustic signals were carried out by nine microphones placed around the illuminating beam not far from the target. Two-dimensional intensity distribution of laser beam obtained by acoustic methods are in good agreement with data obtained by usual photometric method.
