摘要:
A laser light source comprises, in particular, a semiconductor layer sequence (10) having an active layer having at least two active regions (45) which are suitable for emitting electromagnetic radiation during operation via a side area of the semiconductor layer sequence (10) along an emission direction (90), said side area being embodied as a radiation coupling-out area (12), a respective electrical contact area (30) above each of the at least two active regions (45) on a main surface (14) of the semiconductor layer sequence (10), and a surface structure in the main surface (14) of the semiconductor layer sequence (10), wherein the at least two active regions (45) are arranged in a manner spaced apart from one another in the active layer (40) transversely with respect to the emission direction (90), each of the electrical contact areas (30) has a first partial region (31) and a second partial region (32) having a width that increases along the emission direction (90) toward the radiation coupling-out area (12), the surface structure has, between the at least two electrical contact areas (30), at least one first depression (6) along the emission direction (90) and also second depressions (7), and the first partial regions (31) of the electrical contact areas (30) are in each case arranged between at least two second depressions (7).
