Abstract
Multioscillator beam-combining optics having prisms for processing both clockwise and anticlockwise elliptically polarized beams having both helicities transmitted through a partly transmissive corner mirror. The optical structure uses a thin-film polarizer with a waveplate which is not necessarily a quarter wave plate. Further, the waveplate thickness is determined so that one component of elliptically polarized light is converted into a linearly polarized beam. A thin film polarizer then blocks the linearly polarized beam. The waveplate principal crystal axes form a nominally forty five degree angle with the s and p polarization axes. Techniques are used to keep extraneous birefringence of the beams to a minimum.
