Nanostructure Formation on Solid Surfaces melted by Laser Pulse

The paper describes the model of nanostructureformation on solid surface by nanosecond laserpulses melting the material. Stefan problem withcorresponding boundary conditions is solved incombination with nucleation theory. It is found thattypical size of surface nanostructure formeddepends on energy and duration of laser pulse. Forcomparison of theoretic and experimental resultsvarious industry material (germanium, titanium,zirconia dioxide) pieces irradiated by ArF-laser areshown.
