TL;DR: In this article, the authors proposed an additive additive manufacturing (AM) technology that enables the production of light weight structured components with series identical mechanical properties without the need for part specific tooling or downstream sintering processes, etc.

TL;DR: In this article, the authors present a process chain for optics manufacturing with laser radiation, which 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 ablating applies a form correction by removing redundant material.

TL;DR: In this article, the current state of the development of a laser-based process chain for manufacturing fused silica optics is presented, in which a first step fused-silica is ablated with laser radiation to produce the geometry of the optics, a subsequent polishing step reduces the surface roughness and a third step uses micro ablation to remove the last remaining redundant material.

TL;DR: In this paper, the surface roughness of fused silica, borosilicate glass (BK7), and flint glass (S-TIH6) can be reduced significantly.

TL;DR: In this paper, the results of laser polishing as well as laser form correction and combination of the two processes are presented and discussed, and the combination of these two processes is discussed.
