Abstract
A device for shaping the cross-section of a light beam, has at least one beam shaping unit with a beam splitter, beam deflector and beam combiner. The beam splitter can split a light beam which is incident on the beam shaping unit into two partial beams. The beam deflector can deflect at least one of the partial beams onto the beam combiner which can combine the two partial beams in such a manner that the cross-section of the light beam emerging from the beam shaping unit is reduced in size in one direction compared to the light beam incident on the beam shaping unit. The beam combiner is a polarisation-selective beam splitting and beam combination unit that comprises at least two elements with an interface interposed in between. The two split partial beams can be incident on the interface from different directions.
