Flushing Out the Liquid Phase - A New Mechanism of Producing a Crater in Planar Fully Developed Evaporation of a Metallic Target by a Laser Beam
Batanov V.A. , Fedorov V.B.
We examine a new physical mechanism of crater development in a metal acted upon by laser radiation, wherein the liquid metal is ejected from the irradiated region by the reaction vapor-pressure gradient. The mechanism in question is decisive at not too high a radiation intensity. The obtained estimates agree with the experimental data.
