Abstract

A laser arrangement has at least one laser diode apparatus with a side surface which laterally limits the laser diode apparatus. The laser arrangement has a plurality of active regions arranged laterally side by side and configured to generate radiation. The laser diode apparatus is arranged on a mount. The distance between the side surface and an edge which laterally limits the mount on the part of the side surface is shorter than the distance between the side surface and the active region closest to the side surface. Additionally or alternatively, the distance between the side surface and the edge is shorter than one of the distances between two adjacent active regions of the laser diode apparatus.
