Abstract
The interaction between high-power short-pulse laser radiation and a metal target is considered. An analysis is made of the transport of material atoms from the surface layer into the bulk of a semi-infinite sample under the action of the stress field of a plane shock wave and a temperature gradient. The results of numerical calculations for a laser power density of 109 W/cm2 and a pulse length of 30 ns show good agreement with the results of earlier experiments.
