Abstract

Abstract Ultrafast lasers have garnered significant interest in the realm of surface nanofabrication. However, their dynamic electric field distribution is influenced by the polarization direction when pursuing high machining precision, which leads to high polarization dependence of laser nanostructuring. Here, polarization-independent surface nanostructuring is realized on Sb 2 S 3 thin films by femtosecond laser irradiation via a microsphere in the far field and ambient air. The formation of nanogrooves is ascribed to surface thermal stress during melting, re-solidification, and super-cooling under high-repetition-rate femtosecond laser irradiation. The influence of materials melting and ablation on the…
