✦ Synopsis

The two-dimensional Laplace integral transform technique has been applied to get the temperature distributions in the molten layer of a thin-ÿlm coated on a substrate, the solid part of the ÿlm and the substrate during the irradiation with a pulsed laser. The derivation has taken into account the cooling and the temperature-dependent absorption coe cient of the irradiated surface. As an illustrative example computations were carried out on an aluminum thin-ÿlm coated on a glass substrate.
