LASER4SURF has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 768636.A fast and reliable method for the fabrication of polarization modifying devices using femtosecond laser is reported. A setup based on line focusing is used for the generation of LIPSS on stainless steel, processing at different speeds between 0.8 and 2.4 mm/s with constant energy per pulse of 1.4 mJ. SEM and AFM characterizations of the LIPSS show a progressive increase in period as the processing speed increases, while height remains approximately constant in the studied range. Optical characterization of the devices shows an induced change in the polarization of the reflected beam that varies with the processing speed, which allows a controlled fabrication of these devices.engAtribución-NoComercial-SinDerivadas 3.0 Españahttps://creativecommons.org/licenses/by-nc-nd/3.0/es/journal articlehttp://dx.doi.org/10.1016/j.apsusc.2020.146328https://www.sciencedirect.comopen access535Coupled-wave analysisBroad-bandPhotonic structuresForm birefringenceStainless-steelFormulationUniformÓptica (Física)2209.19 Óptica Física
