Abstract

We performed both experimental and theoretical studies on the laser radiation absorption coefficient of a copper surface. A theoretical model for the computation of the absorption coefficient was elaborated for two-layer case (metal-oxide), taking into account the nonlinear processes which govern the dynamics of the temperature and of the widths of the layers. The experimental data and the simulation results proved to be in a very good agreement.
