Abstract:
We present a novel interferometric technique for the accurate measurement of acoustic velocity based on an optical phase shifter consisting of a pair of properly aligned acousto-optic modulators (AOMs). Results for the z-axis longitudinal mode velocities in lead molybdate (PbMoO(4)) and tellurium dioxide (TeO(2)) at 80 MHz are reported and compared with earlier results. A longstanding inconsistency in the PbMoO(4) velocity is resolved.
