Abstract:
1. A surface emitting semiconductor laser, comprising: a first semiconductor layer sequence which comprises a pump laser; a second semiconductor layer sequence arranged on the first semiconductor layer sequence, the second semiconductor layer sequence comprising a vertical emitter having a radiation-emitting active layer, a radiation exit side and a connecting side disposed opposite the radiation exit side, wherein the pump laser is arranged at the radiation exit side of the vertical emitter; and a carrier body arranged at the connecting side of the vertical emitter; wherein the second semiconductor layer sequence has a radiation-emitting region comprising the radiation-emitting active layer; wherein the second semiconductor layer sequence has at least one region that does not emit radiation during operation; and wherein the at least one region that does not emit radiation is formed by a region of the second semiconductor layer sequence that is etched more deeply than the radiation-emitting region in regions around the radiation-emitting region.
