Unraveling power-dependent ablation morphologies, phase transition dynamics, and oxidation mechanisms in femtosecond laser ablation of molybdenum: Experiment and multi-scale modeling

Puntos clave

• Ablation morphologies were significantly influenced by power-dependent dynamics during laser exposure, shaping material outcomes.
• Phase transitions were observed at specific power levels, indicating critical thresholds for material transformations.
• The multi-scale modeling approach provided insights into both the microscopic and macroscopic behaviors of laser ablation.
• Oxidation mechanisms were found to play a crucial role in determining the final morphology of the ablated molybdenum.
