Abstract [en]

The absorptance of the metal surfaces used in Laser Material Processing depends strongly upon the particular surface conditions, including the degree of roughness and oxidation. In this paper the influence of surface topography on Nd:YAG/Nd:YLF laser absorptance has been studied using 3D ray-tracing simulations. The results have increased the understanding of how surface roughness influences the laser-workpiece coupling efficiency.
