Laser light induced dissipative structures on solid surfaces

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The question discussed is related to the formation of different dissipative structures on the surface of metals (vanadium) and the bulk of semiconductors (vanadium pentoxide). Two-dimensional spatial structures of thermal field arise at laser light induced oxidation of metals in both upper and under surfaces. The structures are explained in the theory of instabilities connected with temperature dependence of surface tension of melted material and Benard and Rayleigh-like convections due to temperature gradients caused by laser light.
