Abstract: A general model is derived for computing the temperature profile induced by multi-beam laser irradiation in a semi-infinite substrate. The model is then applied to calculate 2-beam irradiation induced temperature rise in substrate. From this model, it is possible to calculate the temperature profile induced by multi-beam irradiation in substrate. The calculated results show that the double-Gaussian beam has advantages of narrow temperature profile and low heat flow intensity. Flatly-topped temperature profiles can be obtained by converting the Gaussian laser beam.
