Abstract

The results are presented on experimental investigations of action onto an optical glass BK-7 and some other materials of a CO₂ laser radiation with the pulse duration of 20 - 70 microsecond(s) and the energy density of 0.1 - 3 J/cm². The dynamics of a thermal response, temperature of heating and emissivity of irradiated glass samples are under consideration. The results obtained can be used in imaging techniques for objects selection.
