Abstract

In at least one embodiment of the semiconductor laser light source, the latter includes a carrier and at least two semiconductor lasers. The semiconductor lasers are mounted on a carrier top. The semiconductor laser light source furthermore includes at least one optical component, which is arranged downstream of at least one of the semiconductor lasers in a direction of emission. The semiconductor lasers and the optical component are housed tightly in a common enclosure by way of a cover. The dimensions of the enclosure, viewed in three orthogonal spatial directions, amount in each case to at most 8 mm×8 mm×7 mm.
