摘要：

The two-dimensional Laplace integral transform technique has been used to compute the temperature profile of the molten layer on the surface of a semi-infinite target when irradiated by a pulsed laser. Mathematical expressions for the temperature distribution in the molten layer thickness and the solid part of the target, taking cooling and the temperature-dependent absorption coefficient of the irradiated surface into account, were obtained. As an illustrative example computations were carried out on a semi-infinite aluminum (Al) target. (C) 2001 Elsevier Science Ltd. All rights reserved.
