Abstract
In this paper, a novel model is constructed to study the photothermal effects generated in a half-space semiconducting medium by a uniform laser radiation using the modified Green-Lindsay theory. The considered medium is assumed to have temperature-dependent properties. Furthermore, the medium surface is exposed to cooling effect and taken to be traction-free. The obtained mathematical model is treated using Laplace transform, while its inverse obtained numerically. Unlike the existing results, in this work two cases of the surface absorption coefficient are studied with comparisons, and these are constant and temperature-dependent absorption coefficients.
