Ultrafast laser fabrication of biomimetic micro and nano structured surfaces with circular and vectorial polarization states

Abstract

We report on the fabrication of highly ordered, multi-directional, complex surface structures that mimic the unique morphological features of certain species found in nature. In particular femtosecond laser pulses with various polarizations states, such as circular and vectorial, were utilized for structuring metal and dielectric surfaces. Experimental results showed that the direction of LIPSS in each case proved to be polarization dependent which gives as the flexibility to fabricate new and more complex surface structures.
