Figure 1. Schematic of the experimental setup developed for the laser induced fabrication of biomimetic structures.

The incident laser fluence was varied by means of a λ/2 waveplate (HW). The Gaussian profile emitted by the laser source is transformed to a CV beam using a rotating s-waveplate (SW). Depending on the SW rotation angle, the CV beam polarization can be changed from radial to azimuthal respectively.
