We have developed a theoretical model that describes the interaction of intense pulsed flows of energy with matter and is based on the account of local phase transitions at the destruction of a surface. In the frame of a problem concerning the influence of a laser radiation on the surface prior to the beginning of the solid surface destruction, we have solved the equation for the energy flow. The general solution of the equation for the temperature change of a local area of the irradiated solid surface in time is obtained with regard for the coefficient of surface dissipative losses and the volume absorption coefficient. It is shown that the temperature dynamics stimulated by the intense laser radiation depends substantially on properties of the surface layer of the irradiated material.
