Abstract : A laser out put coupler utilizes a bire frigent lens which has one side thereof curved so as to present a nonuniform 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.
