Abstract

Boundary displacements of metal layer illuminated by laser pulse can be found through the investigation of thermoelastic waves. From this point of view the one-dimensional model of generation of thermoelastic waves by light absorption in solids is described and solved, where the exact thermal and mechanical boundary conditions were used. Using this model the amplitudes of both sample surfaces displacements as functions of the duration of the incident light pulse are determined. 1 Introduction The theoretical treatment of thermoelastic wave generation was originally given by Danilovskaya [1], who used idealized assumptions for heating. Michaels [2] chose the heating conditions more carefully, although heat diffusion was still not considered. Boley and Tolins [3] additionally
