Laser module and scanner projector

A scanner projector, comprising:

• 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.

A method for generating an overall laser beam from multiple laser beams, comprising:

• emitting a laser beam in each case from a different laser light source;
• coupling a laser beam of a first laser light source having a first polarization into the overall laser beam;
• coupling a laser beam of a third laser light source having a second polarization into the overall laser beam;
• splitting a laser beam of the second laser light source having the first polarization into a main path and a splitting path, in the splitting path the first polarization of the laser beam of the second laser light source being changed from the first polarization to the second polarization;
• and
• coupling the laser beam of the second laser light source into the overall laser beam via the main path and via the splitting path.
