title: Laser interferometer with a multicentimeter sensitivity.
abstract: An optical interferometer based on phase conjugation by stimulated Brillouin scattering is demonstrated. Two scattered orders from a phase grating provide the light input to the two arms of the interferometer. Phase conjugation eliminates all phase differences between the electric fields in the two arms except those that are due to the frequency shift of the stimulated Brillouin process.
