Description

It is shown in the paper, that two mechanisms of particle detachment from the surface, comparable by efficiency, - cluster (non-drop) and drop ones -are used in interaction of pulsed laser radiation with the surface of YBaCuO target. There exists some boundary of radiation power density Wimp=2.5·108 W/cm2, below which the drop mechanism is realized even in absorption of one pulse, and above which (Wimp>Wimp1) the cluster mechanism is realized during some delay time τd. The drop mechanism is realized at t>τd. Delay time τd grows with increase of Wimp and target density ρ; τd is proportional to ρ at Wimp>Wimp1. 16 refs.; 4 figs
