Pulsed Laser Heating of a Finite Silver Selenide Slab Using (HHCE) Model

Abstract

Heat induced in a finite Silver Selenide slab by an external pulsed laser source is studied in dimensionless scale according to hyperbolic heat conduction model (HHCE) using Laplace integral transform technique. The temperature profile, the critical time required to initiate phase transition and that to initiate damage at the front surface are obtained for different pulses and are illustrated graphically.
