Abstract
In one embodiment, the invention relates to a semiconductor laser comprising a semiconductor layer sequence for generating laser radiation. According to the invention, the semiconductor layer sequence has a geometric structuring on a top side. A resonator is located in the semiconductor layer sequence and is delimited by opposing facets, wherein the facets contain optically active resonator end faces. The structuring ends spaced apart from the facets. The resonator end faces are spaced apart from material removals from the semiconductor layer sequence.
