Sažetak

During the last years, the self-cleaning surface structures of lotus flowers have been reproduced in numerous ways on textiles or paintings and other surfaces to reduce sensitivity against pollution which, in turn, allows a reduction of water- and detergent consumption. Unfortunately, some of these techniques suffer from wear or are potentially biohazardous due to the small particle size. We present a method to produce nanostructures on surfaces by multi-beam interference of ultra-short laser pulses. Expected intensity distributions, as well as ablation rates of various configurations have been simulated and show the feasibility of the suggested process.
