Abstract

The invention relates to a laser light source (100) comprising a plurality of surface emitters (200, 200a, 200b,...) which are arranged on a substrate element (300). The invention is characterized in that different surface emitters (200a, 200b) are each designed and/or arranged relative to one another on the substrate element (300) such that main beam directions (H1, H2) of the laser radiation emitted from said emitters are not parallel to one another and/or such that a packing density which describes a distance from a first surface emitter (200c) to at least one surface emitter (200d) that is adjacent to the first surface emitter in at least one dimension is not constant.
