Abstract
The present invention relates to a surface-emitting semiconductor laser having a vertical resonator, comprising a substrate base section (1) and a mesa (M) arranged on and/or at the substrate base section, the mesa substantially comprising, viewed perpendicular to the substrate base section: at least one part of a first doting region (2) facing the substrate base section, at least one part of a second doping region (4) facing away from the substrate base section, and an active region (3) arranged between the first and the second doping regions, said active region having at least one active layer (A) with a laser-emitting zone, emitting substantially perpendicular to the active layer, characterized in that the mesa (M) comprises in at least one partial section of the side flank thereof at least one constriction (E).
