Abstract

Solid-liquid phase transitions induced in monocrystalline GaAs by nanopulsed radiation of a ruby laser were studied by means of time-resolved reflectivity and pyrometric measurements. GaAs samples were irradiated in transparent liquid media (alcohol’s and toluene) or in air ambient. Dependencies of the peak temperature and melt duration on laser energy density have been determined. Experimental data obtained for a case of irradiation of GaAs samples in air are compared with the results of computer simulation of the laser-induced phase transitions.
