Abstract
ABSTRACT: In this paper, the laser short-pulse heating of a solid surface is considered. The time fractional heat conduction model is used as the constitutive heat diffusion model and the corresponding fractional heat conduction equation with a volumetric heat source is built. Inverse Laplace transform is applied to obtain the analytical solution for non Gaussian type laser. The numerical results are presented graphically for various values of model parameters. Fractional order parameter only influences the magnitude of temperature rising, having no effects on the speed of heat propagation. Higher the temperature rise, larger the fractional order parameter. This research provides some new points for further studying the laser heating or other non-Fourier heat conduction problems.
