Fourier equation does not accurately predict the transient temperature during microscale laser heating of thin films. Therefore, non-Fourier behaviors may be significant for such microscale applications as pulsed-laser processing of metal and semiconductors, thin-film applications, and even laser surgery. A numerical model is developed to represent the temperature distribution during ultra short pulsed laser processing of aluminum thin films. The model developed is based on the solution of non-Fourier heat conduction problem with different thermal fluxes using explicit finite differences method. A computer program Quick-Basic language was built to perform the solution. The results of Non-Fourier heat conduction equation were compared with the results of Fourier heat conduction equation and showed that when the time increased Non-Fourier equation will be Fourier equation. The results showed that when increased the heat flux greater than the problem convert from one-dimensional non-Fourier heat conduction to one-dimensional non-Fourier phase change.
