The Experimental and Modeling Study of Femtosecond Laser-Ablated Silicon Surface

Journal of Manufacturing and Materials Processing, 2023
In this study, monocrystalline silicon was ablated by a single 1030 nm femtosecond laser pulse. Variable laser fluence (0.16–3.06 J/cm2) was used, and two ablation thresholds (0.8 and 1.67 J/cm2) were determined experimentally.
