Laser evaporation of metal in gaseous atmosphere
Abstract
A gasdynamic theory is presented of the evaporation of metals by laser radiation in a wide range of external pressures for power densities of 1 to 100 MW/sq cm. The boundary between the supersonic gasdynamic and the diffusive evaporation regimes is established. The results of numerical calculations of the evaporation of aluminum and iron are presented.
