Our work is to improve the surface texturing process by laser irradiation. In this study, thermal modelling of the laser-matter interaction for a single laser impact case is presented.

A 1D modelling was carried out. The purpose was to determine the dimension of the liquid layer and the ablated matter volume.

The model accounts for the evolution of material thermodynamic properties, the matter ablation, and the molten metal motion.
