Patent ID: 8879597

Claim:
An optoelectronic semiconductor laser comprising: a growth substrate, a semiconductor layer sequence that generates laser radiation, a front facet at the growth substrate and at the semiconductor layer sequence which constitutes a main light exit side for the laser radiation generated in the semiconductor laser and has a light exit region at the semiconductor layer sequence, a light blocking layer for the laser radiation, which partly covers at least the growth substrate at the front facet such that the light exit region is not covered by the light blocking layer, and a bonding pad at a side of the semiconductor layer sequence facing away from the growth substrate, wherein the light blocking layer comprises first and second partial layers alternately succeeding one another, the partial layers, with a tolerance of at most λ/7, have an optical thickness of λ/4, the first and/or the second partial layers comprise a material that is absorbent for laser radiation having the wavelength λ, the light blocking layer comprises 2 to 20 of the partial layers, and a distance between the bonding pad and the light blocking layer at least at the light exit region is 0.1 μm to 100 μm.
