Abstract

An apparatus for combining a plurality of coherent laser beams includes at least N−1 phase setting devices configured to set a respective phase (δφn) of a respective one of the plurality of coherent laser beams, and a beam combination device configured to combine the plurality of coherent laser beams to form at least one combined laser beam. The beam combination device includes a microlens arrangement having at least two microlens arrays configured to form the at least one combined laser beam.
