BEAM SHAPING DEVICE FOR SHAPING THE CROSS-SECTION OF A LIGHT BEAM AND SYSTEM FOR LAUNCHING INTO AN OPTICAL FIBER A LIGHT BEAM HAVING AN ELONGATED CROSS-SECTION AND BEING EMITTED BY AN ELONGATED LASER BEAM SOURCE
BEAM SHAPING DEVICE FOR SHAPING THE CROSS-SECTION OF A LIGHT BEAM AND SYSTEM FOR LAUNCHING INTO AN OPTICAL FIBER A LIGHT BEAM HAVING AN ELONGATED CROSS-SECTION AND BEING EMITTED BY AN ELONGATED LASER BEAM SOURCE
The invention relates to a beam shaping device for shaping the cross-section of a light beam, comprising at least one beam shaping unit with beam splitting means, beam deflecting means, and beam combination means. The beam splitting means are capable of diving up a light beam that is incident on the beam shaping unit into two partial beams. The beam deflecting means are capable of deflecting at least one of the partial beams onto the beam combination means and said beam combination means are capable of combining the two partial beams in such a manner that the cross-section of the light beam exiting the beam shaping unit is reduced in size in a first direction compared to the cross-section of the light beam that is incident on the beam shaping unit and is increased in size in a second direction perpendicular thereto. the invention is further characterized in that the beam combination means can also be used as beam splitting means, whereby only one of the partial beams is deflected by the beam deflecting means, while the other partial beam is directly incident on the beam combination means.
