Sažetak
We have shown that nanosecond laser– matter interaction with metal surface under an angle causes the formation of nonlinear micron-scale waves and localized structures resembling the gravitationally caused flow structures on the inclined plate. Juxtapostion of experimentally generated and numerically simulated structures on the basis of the equation derived by A.L.Frenkel and K.Indireshkumar  Phys.Rev, E55 1174 (1997) shows a very good qualitative agreement ; the experiments confirmed the dependence of the structure evolution on the laser power profile and on the irradiation angle. Dispersion of ordered long-range structures into chaotic ones was observed for the irradiation angle of  =200.
