Current results of the development of a process chain for optics manufacturing with laser radiation are presented. The process chain consists of three process steps: High Speed Laser Ablation creates the surface geometry by material ablation, Laser Polishing reduces the surface roughness by material remelting and High Precision Laser Ablation applies a form correction by removing redundant material. Compared to conventional optics manufacturing methods, this process chain benefits from its high flexibility concerning the optics geometry and its processing speed, which is independent from the processed geometry.
