Abstract
In one embodiment the semiconductor laser () comprises a carrier () and an edge-emitting laser diode () which is mounted on the carrier () and which comprises an active zone () for generating a laser radiation (L) and a facet () with a radiation exit region (). The semiconductor laser () further comprises a protective cover (), preferably a lens for collimation of the laser radiation (L). The protective cover () is fastened to the facet () and to a side surface () of the carrier () by means of an adhesive (). A mean distance between a light entrance side () of the protective cover () and the facet () is at most 60 μm. The semiconductor laser () is configured to be operated in a normal atmosphere without additional gas-tight encapsulation.
