Abstract

We have derived an axially symmetric three-dimensional analytical solution for thermoelastic deformations and stresses in a layered medium irradiated by a laser beam. The solution was obtained for Gaussian radial temperature profile on the upper surface of the elastic layer, in the assumption that temperature decreases exponentially with depth. The developed theoretical model was used to calculate distributions of laser-induced deformations and displacements in a medium containing single layer over a half-space. The influence of the shear elastic properties of the layer and half-space on the stress and strain distributions was evaluated. It was shown that tissue response depends significantly on the elastic contrast between the layer and the half-space. The proposed solution could be used in photomechanical models of laser ablation of inhomogeneous materials and tissues.
