Laser light induced dissipative structures on solid surfaces

The question discussed in this paper are 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 arised at laser light induced oxidation of metals in both upper and under surfaces are presented. The observed structures are explained in frames of theory of instabilities connected with temperature dependence of surface tension of melted material Benard and Rayleigh like convections due to temperature gradients caused by laser light. 1.
