Abstract

A bleaching effect of a strong absorbing fluid by a short laser pulse is investigated for the layer depth of the order of the absorption length under assumption of the linear relation between the fluid density and absorption coefficient. Gaussian and ring perpendicular intensity distributions of beams are considered. Space and time evolution of the basic parameters of the interacting matter and radiation are calculated -- density, temperature, pressure, specific inner energy, fluid velocity, radiation intensity. A satisfactory agreement is found for the theoretical and experimental transparency function dependence on the pulse energy.
