“…In addition, the possibility to control the LIPSS distribution within the focal spot by choosing a certain beam profile leads to an extension of the current state-of-the-art and, thus, to a higher flexibility of the direct-writing structuring method. The fluence values calculated above for the top-hat profile are comparable with the fluence required for ablation-based LIPSS formation on stainless-steel at comparable irradiation parameters [30,31].…”

“…In this context, the specific optical properties make stainless-steel a well-suited candidate for the production of highly regular LIPSS [ 31 ]. This concerns in particular the exact alignment and a small dispersion of the spatial frequencies of the LIPSS, which are coherently linked to each other despite the unidirectional scanning procedure [ 30 , 31 ].…”

“…Macroscopic elastic deformations affect the microscale by slightly changing the periodicity of the gratings responsible for the holographic colors. This has been systematically reported in the recent work of Gräf, where the effects of the work piece's deformation have been correlated with the microscopic deformation of the gratings, thus changing the colors they diffract. For the approaches presented in this work, the surface is patterned with different microgratings, and consequently any macroscopic deformation would modify the periodicity of the microgratings in the same relative amount.…”

“…LIPSS [65,66,67,68], a universal phenomenon that occurs after laser irradiation on a wide number of different materials [69,70,71], have been found to exhibit different characteristic shapes, including ripples (lines), rods, cones, grooves, etc. The generation of LIPSS takes place commonly only in a fluence range close to the material damage threshold and even just below the ablation threshold [72].…”
