Beschreibung
Zusammenfassung:	An apparatus for combining a plurality of coherent laser beams includes a splitting device configured to split an input laser beam into the plurality of coherent laser beams, a plurality of phase setting devices configured to adjust a respective phase of one of the plurality of coherent laser beams, and a beam combining device configured to combine the plurality of coherent laser beams, which emanate from a plurality of grid positions of a grid arrangement. The beam combining device includes a microlens arrangement having at least two microlens arrays. The apparatus further includes a controller configured to adjust a respective phase of a respective one of the plurality of coherent laser beams and/or vary a respective phase of a respective one of the plurality of coherent laser beams.
