A major change in the properties of material surfaces caused by laser-induced periodic surface structures (LIPSS) can be found useful in the field of optics and energy technology. Using the example of increasing the efficiency of solar cells, it was shown that the reflection and absorption behavior can be specifically modified by micro- and nanostructuring of the surface. This technology can also be used to create anti-reflective surfaces, similar to those of the glass wing moth (Greta oto) or the moth eye. In this work-controlled generation of 1D and 2D structure on thin titanium film is demonstrated. The optical property of the generated structures is studied in the visible region, in order to create a protective hologram.
