Abstract

A phenomenological model is suggested for near-surface laser plasma initiation for the case of short durations of the ignition process (t*-7 sec). The model takes into account the dependence of the surface defect's absorptivity on its size and the local concentration of defects. A comparison of calculated and experimentally obtained values of plasma initiation duration is carried out.
