Optical arrangement e.g. gas laser, for forming laser beam, has unit from wave plate, where beam, which can be formed, is divided into two partial beams of different polarizations by unit from wave plate

摘要

The arrangement has a unit from a wave plate, where beam, which can be formed, is divided into two partial beams of different polarizations by the unit from the wave plate. The two partial beams have approximately equal power or energy. The partial beams are refracted by utilization of a prism in such a manner that both the partial beams of different polarizations intersect in a propagation direction and are superimposed in accordance with the intensity.
