Abstract

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.
