The ability of lasers to controllably deposit energy in a highly confined surface layer is basis of many applications in surface-morphology science and technology with nano-and micro-meter scale.In this presentation femtosecond laser surface processing of metals,including laser direct writing and laser-induced periodic surface structures (LIPSS),are investigated in order to provide topographic and hydrophobic properties.For micro-patterns fabricated by laser direct writing,femtosecond laser pulse with 780nm wavelength is used to etch the substrate surface to form different controlled patterns.The depth of etched grooves,the clearance between tow grooves and the width of grooves are optimized to obtain the hydrophobic surfaces.For the LIPSS,a gradual evolution of surface topography of nano-and micro-periodic ripples and microspikes are induced with various levels of femtosecond laser fluence and pulse number.The morphology and size of the LIPSS can be controlled by varying the levels of laser fluence and pulse number.The hydrophobic properpies are discussed based on the morphology characteristics and the relationship among laser processing parameters.In order to obtain surperhydrophobic surfaces,the surface topography with nano-and micro-patterns are fabricated by using laser direct writing combined with LIPSS.
