Disclosed are optical arrangements including: a disk-shaped laser-active medium, a deflecting device, having a plurality of mirror elements on which mirror faces for deflecting a laser beam are formed, and having a base body on which the mirror elements are fastened, the mirror faces of the mirror elements being oriented in such a way that the laser beam is deflected by a respective mirror face via the disk-shaped laser-active medium to another mirror face. The mirror elements are formed in one piece or are monolithically joined, and have a connecting section that is formed rotationally symmetrically with respect to a center axis and is rigidly connected by a material-fit connection or a direct connection to the base body.

Optical arrangements with disk-shaped laser-active mediums

This disclosure relates to laser disk mounting systems and methods. The laser disk mounting systems comprise a disk module with a round disk-shaped heat sink having a front side, a rear side, and an edge surface connecting the front side and the rear side, and a laser disk arranged on the front side of the heat sink, and a radial mounting device with an opening for receiving the disk module, wherein the disk module is mounted in the radial mounting device such that a force action is applied in radial direction on the edge surface.

Stress-optimized laser disk mounting systems

This disclosure relates to pumping light systems and methods for using a disc laser. A focusing device with a reflecting surface focuses a pumping light beam onto a laser-active medium. A deflecting system deflects the pumping light beam between reflecting regions formed on the reflecting surface that are arranged in different angle regions around a central axis of the reflecting surface in at least a first annular region and a second annular region. The deflecting systems are configured to perform at least one deflection of the pumping light beam between two reflecting regions of the first annular region and at least one deflection between two reflecting regions of the second annular region.

Pumping light systems for disc lasers

A solid-state laser arrangement includes a plate-like solid body including a laser-active medium, a heat sink, a layer of adhesive between a carrier face of the heat sink and the plate-like solid body, and a reflective coating on a side of the plate-like solid body facing the adhesive layer, in which the adhesive layer is completely shielded from radiation from the plate-like solid body by a radiation-impermeable region between the side of the plate-like solid body facing the adhesive layer and the carrier face of the heat sink.
