摘要:
An edge emitting semiconductor laser includes a semiconductor body having a wave guide area. The wave guide area comprises a lower cover layer, a lower wave guide layer, an active layer for generating laser radiation, an upper wave guide layer and an upper cover layer. The wave guide area also includes at least one structured laser radiation scattering area in which a lateral base laser radiation mode experiences less scattering losses than the radiation of higher laser modes.
