Sažetak
We have shown that laser surface processing under an angle generates surface morphology which comprises localized structures analogous to gravitationally caused nonlinear instabilities on the inclined plate. The presence of the low and the high melting (boiling) point metal and nonmetal impurities causes instability evolution at the rate much higher than on the pure metal. The uid surface dynamics inuenced by impurities causes formation of irregular long-range structures in the peripheral regions, and irregular short range ones in the central regions of the spot. Thus, chaotic dynamics appears in the whole interaction space, indicating the loss of memory of the initial conditions.
