The PolySense team has just published a new article on Optics & Laser Technology journal reporting on a study of the generation of Laser-Induced Periodic Surface Structures (LIPSS) on quartz upon irradiation with linearly polarized femto-second laser pulses (pulse duration τ = 200 fs and central wavelength λ = 1030 nm). Two different regimes of LIPSS were observed, Low-Spatial-Frequency-LIPSS (LSFL) and High-Spatial-Frequency-LIPSS (HSFL), characterized by different spatial periods and orientations. Extended HSFL patterns (25 × 25 mm2) were realized, and their wettability was compared to that of pristine quartz. Contact angle measurements showed that HSFL textured quartz exhibits a super-hydrophilic behaviour, with a measured contact angle equal to 7.6°, with respect to pristine quartz which results simply hydrophilic and shows a contact angle equal to 41.2°.
