Hyperbolic two-step micro heat transport equations have attracted attention in thermal analysis of thin metal films exposed to ultrashort-pulsed lasers. In this talk, we present a finite difference scheme for studying thermal deformation in a 2D double-layered micro thin film exposed to ultrashort-pulsed lasers. This scheme is obtained based on the hyperbolic two-step model with temperature-dependent thermal properties. The method is illustrated by investigating the heat transfer in a gold layer padding on a chromium layer. Result shows that there are not non-physical oscillations in the solution.
