Abstract

For laser applications very smooth surfaces are required more frequently. High power systems need components, such as cavity mirrors and lenses for beam forming and focussing, with extremely high laser damage threshold. In low power systems for metrology any light scattering originating from a relatively high surface roughness results in measuring errors. In both cases flat and curved surfaces with very low micro-roughness rms values close to 1 nm or even less have to be produced. This requires the optimization of the polishing process. Minimized surface roughness and light scattering are shown as results of this optimization.
