摘要: Fractal dendritic silver microstructures are observed on the surface of Ag+-doped glasses as a result photothermal interaction with focused multiline cw high-power (Pmax=8 W) Ag+ laser beam. It is found that evolution structures depends exposure time and also concentration ions in sample. The fractal dimension generated increases time. Instability contact line molten flow toward periphery area discussed temperature gradient, due to Gaussian intensity distribution across
