Abstract
A semiconductor laser component includes a semiconductor body with an SCH configuration which is suitable for generating an electromagnetic radiation and in which an active layer sequence with a quantum well structure is provided between a first outer cover layer of a first conductivity type and a second outer cover layer of the first conductivity type. A first denatured transition layer of a second conductivity type and a second denatured transition layer the first conductivity type are provided between the active layer sequence and the second outer cover layer.
