| 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. |

| Keywords: | non-Fourier effect semi-analytic solution integral transform thermal relaxation time |
