Two Temperature Model for Metals: A New “Radical” Approach
M. Oane, M. Tacaand S.L. Tsaoi
In this paper we present a new approach to build a laser-metal thermal interaction model with consideration of solving the two temperatures: electron and phonon temperatures. Using only one Fourier equation we can get information about the three-dimensional thermal fields, surface temperature and steady state quantum effects temperature while the laser beam impinges on the surface of a metal. We apply the integral transform technique with merging of the Anisimov and Nolte models.
