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 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. 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.

Abstract: In one embodiment the semiconductor laser (1) comprises a carrier (2) and an edge-emitting laser diode (3) which is mounted on the carrier (2) and which comprises an active zone (33) for generating a laser radiation (L) and a facet (30) with a radiation exit region (31). The semiconductor laser (1) further comprises a protective cover (4), preferably a lens for collimation of the laser radiation (L). The protective cover (4) is fastened to the facet (30) and to a side surface (20) of the carrier (2) by means of an adhesive (5). A mean distance between a light entrance side (41) of the protective cover (4) and the facet (30) is at most 60 μm. The semiconductor laser (1) is configured to be operated in a normal atmosphere without additional gas-tight encapsulation.
