  • Output coupler for laser resonator
    Patent number: 4461009
    Abstract: A laser output coupler utilizes a birefrigent lens which has one side thereof curved so as to present a non-uniform polarization distribution across the face of the lens. A polarized beam splitter is employed to separate the output beam from the feedback beam; the feedback beam having a non uniform distribution across the laser aperture enhances mode discrimination of a pulsed resonator.
