title: Beam quality of acousto-optic frequency shifters.
abstract: The beam quality of the diffracted wave from a bulk acousto-optic frequency shifter has been accurately measured. High accuracy in measuring the output-phase profile was achieved by a unique utilization of heterodyne interferometry. Results for glass and PbMoO(4) deflectors show no discernible beam-quality degradation attributible to the acousto-optic interaction to within 0.01 wave rms at 647.1 nm.
