Abstract:
1. A semiconductor laser, comprising: a semiconductor body having a first main area, a second main area, a resonator axis, an active layer disposed parallel to said resonator axis and between said first and second main areas, a first mirror area, and a second mirror area, said first and second mirror areas disposed substantially perpendicularly to said resonator axis; at least one current-carrying layer formed in said semiconductor body; and at least one strip-type resistance region disposed in said current-carrying layer and running transversely with respect to said resonator axis, said strip-type resistance region having a sheet resistivity being increased at least in partial regions compared with regions of said current-carrying layer adjoining said strip-type resistance region; said sheet resistivity of said strip-type resistance region being lower in a first partial region than in a second partial region, said first partial region being at a shorter distance from said resonator axis than said second partial region.
