Abstract

This paper deals with the problems of dynamics of laser(IR)-induced surface processes. It refers somewhat to laser-induced gas-phase processes near a solid surface and processes of adsorption and desorption in the frame at nonequilibrium thermodynamics. The main attention is devoted to the processes of laser-induced structure formation (metal oxidation) based on pure thermal effects of laser light, both in the solid and liquid phase. Fundamental results of the theory of nonlinear dynamics are used to systematize the experimentally observed thermal oscillations and pattern formation due to hydrodynamic flows appearing from CO2 and YAG laser induced oxidation of metallic foils. The fractal conception is applied to the surface morphology characterization of oxide layer grown in the laser field.
