The micromechanical properties of GaP single crystals exposed to pulsed laser irradiation

The results of pulsed laser radiation action (UV region) on the mechanical properties (microhardness, fragility, density, and behavior of dislocations) of GaP crystals are presented. It is established that the action of laser radiation in situ generally results in the hardening of the surface layer...
