Abstract
⺠Glancing absorptivity of 1 μm lasers across a wavy molten steel surface. ⺠Even low roughness causes strong, complex local absorptivity modulation. ⺠For moderate and high roughness shadow domains gradually lower absorptance. ⺠Important consequences for laser welding, cutting, drilling. ⺠Angle- and wavelength-dependent Fresnel-curves determine absorption at rough surfaces.
