Within the framework of a dynamic uncoupled problem of thermoelasticity for a half-space, the effect of pulsed laser radiation on glassy and ceramic materials is considered. Analytical relations are obtained, which are the criteria for the thermal strength of materials for three temporal forms of laser pulses of nanosecond duration and make it possible to determine non-destructive annealing modes. The influence of the temporal shape of the laser pulse on the annealing regimes of materials is shown. It was found that the use of laser pulses with a steep front and a protracted falloff leads to a decrease in thermoelastic stresses in the material.
