Light-emitting device and method for emitting light

A light-emitting device, comprising:

• a laser light device configured to emit a multiplicity of laser light beams, ellipticities of beam cross-sections of the laser light beams differing at least partly from one another;
• a beamforming device in the beam path of at least one of the laser light beams and configured to adapt the ellipticities of the beam cross-sections of the laser light beams to one another by adapting a major axis and a minor axis of the beam cross-section of the at least one laser light beam to one another;
• a beam-combining device configured to combine the laser light beams to form an overall light beam, after the adapting of the ellipticities of the beam cross-sections by the beamforming device;
• and
• a further beamforming device situated in the beam path of the overall light beam and that is designed to correct an ellipticity of a cross-section of the overall light beam.

• wherein the beamforming device is configured to adapt the ellipticities in such a way that the ellipticities of the beam cross-sections of the laser light beams each lie in a specified range between 1.5 and 2.5, after the adapting.
