Patent ID: 6947464

Claim:
A semiconductor laser device, having an epitaxial semiconductor body ( 40 ) with a waveguiding layer ( 22 ), which contains an active radiation-generating layer ( 20 ), a laser-active emitter region ( 12 ), disposed in the epitaxial semiconductor body ( 40 ) and having a primary direction ( 30 ), which essentially corresponds to the exit direction of the laser radiation from the emitter region, and an amplifier region ( 14 ), adjoining the emitter region ( 12 ) in the semiconductor body ( 40 ) in the primary direction ( 30 ), for amplifying the laser radiation, wherein the emitter region ( 12 ) and the amplifier region ( 14 ) form active regions in the semiconductor material, characterized in that the waveguiding layer ( 22 ) is at least partly removed in some regions of the semiconductor body ( 40 ) outside the active regions ( 12 , 14 ), in such a way that flanks ( 18 ; 32 ; 36 ) of the semiconductor body ( 40 ) that are produced by the removal form a shallow angle τ with a plane in which lies said waveguiding layer.
