These mirrors create a 90° Phase Shift with the aid of specially constructed thin film coating x-layers applied to the surface, when hit with a linear polarized beam at 45° to the plane of incidence. Commonly called Phase Shifters, Polarizers, or Circular Polarizing Mirrors, they tranform the incoming beam into a circular polarized state. They typically are only used external to the laser cavity as a beam delivery mirror. These operate only with a true 10.6μm laser wavelength and will not work at other wavelengths such as 9.2 or 9.6μm without special modifications to the thin film coating design. We offer non-standard wavelength Phase Retardation Reflectors at these other wavelengths as custom parts.
