Abstract
A simple heterodyning technique is described that permits a rigorous measurement of the phase-conjugate fraction of a scattered beam in Brillouin scattering. A general expression for interferometry using phase-conjugate mirrors is derived. The applications of the technique to the measurement of laser phase structure and intensity-dependent phase shifts, and also for high-resolution determination of Brillouin acoustic frequencies, are discussed.
