Abstract: Known power lasers have outstanding electrical, optical and mechanical properties, in spite of different temperature conditions during switching on and during operation. However, they are expensive. These properties are retained, despite cheaper production costs in that, starting from a solid monolithic optical bench, several mirror blocks and intermediate blocks are mechanically rigidly connected to this, and are shaped such that they do not deflect during chip-removing machining, and those bores necessary for the laser path are only then provided.

Abstract: A connector assembly for resiliently actuated coupling of a first component of cylindrical configuration to a second component with a cylindrical recess utilizes a pair of interfitting inner and outer annular ring elements having first and second axial ends and axially extending overlying body portions. The first ends extend inwardly of the recess and the second ends are in surface contact with the circumferential surface of the cylindrical component. Each ring elements has a radially extending flange on one of its ends which extends along the ends of the other ring element into close surface relationship with one of the components.
