Abstract: The non-Fourier model of heat transfer as a laser pulse irritating on surface of material with large thermal relaxation time is considered.A new semi-analytic solution is derived by using Laplace,Hankel and their inverse transforms.By numerically simulating the solution,the wave form behavior of temperature can be seen clearly.

Key words: non-Fourier effect, semi-analytic solution, integral transform, thermal relaxation time
