Quasi-steady vaporization of a sphere by intense continuous-spectrum radiation
Abstract
A theoretical study is presented of the vaporization of a spherical metallic target by intense CW laser radiation. It is assumed that the motion of vapor heated by the laser radiation is radially symmetric. Results are presented for an aluminum sphere with a radius of 1 cm for the case of an incident radiation flux density of 33 GW/sq cm (corresponding to a temperature of 24 eV). It is shown that the laser radiation can produce a high-velocity steady flow of dense hot plasma.
