Abstract

Laser shock hardening consists in the action on a sample of a pressure pulse generated by the plasma of the sample surface layer vaporized by short high-energy laser pulses. To model the change in the properties of the material under the action of pulsed mechanical stresses, it is necessary to know the space-time dependence of the pressure acting on the sample subject to the parameters of the laser pulse and the properties of the evaporated material. This paper presents a model and calculation of the time dependence of the pressure acting on a sample as a result of evaporation of the absorbing material and the development of plasma optical breakdown.
