Phase Retarding Mirrors are designed to produce a specific phase shift between the S and P polarization components of an incident CO2 laser beam. Mirrors designed for zero phase shift maintain the incident polarization state in the reflected beam. Mirrors designed for λ/4 (90º) phase shift convert a linearly polarized beam into a circularly polarized beam. Mirrors designed for λ/8 (45º) phase shift convert a linearly polarized beam into an elliptically polarized beam. |
