Abstract

A technique is presented for solving the problem of the thermomechanical effect of a pulsed laser beam on an absorbing medium, based on the numerical simulation of three-dimensional equations of the motion of continuous media in the Lagrange form. The structure of the excited acoustic pulses is analyzed depending on the space-time characteristics of the laser pulses.
