Phase transition induced by CW-laser in a finite silver selenide (Ag2 Se) according to (HHCE) model

Abstract

Thermal effects induced in a finite silver selenide slab by CW laser source are studied. The hyperbolic heat conduction equation (HHCE) in dimensionless form is solved using Laplace integral transform technique. Different laser power densities are considered. Expression for the temperature field within the target is obtained. As an illustrative example, the critical time required to initiate phase transition and that required to initiate melting are computed for different pulses.
