Non-Gaussian laser pulse response on photo-thermoelastic interactions in a silicon plate under the light of memory-dependent thermoelasticity theory

In the present article, the wave propagation in a homogeneous semi-infinite silicon plate through photo-thermal process has been comparatively studied under the light of memory-dependent thermoelasticity theories with thermal relaxations. Without neglecting the coupling between the plasma and thermoelastic waves that photo-generated through intensity modulated beam of non-Gaussian laser pulse, a two-dimensional semiconducting medium having homogeneity in thermal and elastic properties is considered. The analytical solutions were observed in the domain of Laplace–Fourier transform by the method of eigenvalues approach. Finally, suitable graphical discussions and conclusions are presented with respect to varied thermal relaxation times.
