Abstract:
1. A laser module, comprising: a first laser light source; a second laser light source; and a third laser light source, wherein: laser beams of the first, second, and third laser light sources are combinable to form an overall laser beam, the laser beam of the first laser light source and the laser beam of the second laser light source have a first polarization, and the laser beam of the third laser light source has a second polarization, the laser beams of the first and the third laser light sources are coupled into the overall laser beam with the aid of mirror devices, the laser beam of the second laser light source is split, the first polarization of the laser beam of the second laser light source is changed from the first polarization to the second polarization in a splitting path, the laser beam of the second laser light source having the second polarization is coupled into the overall laser beam via the splitting path, and the laser beam of the second laser light source having the first polarization is coupled into the overall laser beam via a main path.
