Analytical solution for laser short-pulse heating of a micro-sized metal wire is presented. In the analysis, volumetric and surface heat sources are incorporated same pulse intensity. The source resembles absorption by irradiated field according to Lambert’s Beer law while represents short through high intensity thermal contact at surface. method Lie point symmetries combined with Fourier cosine transformation solve temperature equation appropriate boundary conditions. It found that profiles differ significantly considerations; in which case, consideration results considerably lower temperatures than consideration.
