Abstract

This study explores the effects of femtosecond laser pulses on Zinc Selenide (ZnSe), Germanium (Ge), and Silicon (Si), emphasizing laser-induced breakdown and the formation of Laser-Induced Periodic Surface Structures (LIPSS). Employing a 5.8 µm wavelength light at a 9 µJ per pulse energy, we document the ablation and structural changes in 5 mm thick samples. Our findings highlight the distinct responses of these materials to ultrafast, intense energy pulses, particularly noting the formation of LIPSS on ZnSe with a periodicity ∼1.5 times the wavelength of the incident light. These insights contribute to the broader understanding of material behavior under extreme laser conditions, offering avenues for advanced material patterning and surface engineering.
