Abstract

The invention relates to a laser light source (340, 340a, 340b, 340c, 340d, 340e) having a semiconductor laser chip (341, 341a, 341b), having a plurality of emitters (342) which emit laser light. According to the invention, provision is made of at least two cooling elements (345a, 345b, 345c) for cooling the semiconductor laser chip (341, 341a, 341b) which are situated in thermal contact with two different surfaces (341', 341') of the semiconductor laser chip (341, 341a, 341b).
