Abstract
A semiconductor laser diode includes a semiconductor body having an emitter region; and a first connection element that electrically contacts the semiconductor body in the emitter region, wherein the semiconductor body is in contact with the first connection element in the emitter region, and at least in places in the emitter region, the semiconductor body has a structuring that enlarges a contact area between the semiconductor body and the first connection element.
