The effect of pulsed laser radiation on glassy and ceramic materials is examined within the scope of the dynamic uncoupled problem of thermoelasticity for a half-space. Analytical relations expressing the thermal strength criteria for materials are obtained with three temporal shapes of laser pulses of nanosecond duration, making it possible to determine non-destructive regimes of annealing. The impact of the temporal shape of a laser pulse on the annealing regimes of materials is shown. It is found that laser pulses with a steep leading edge and a protracted trailing edge give thermoelastic stress reduction in the material.
