Abstract
A laser-diode (LD) heterodyne interferometer with a BaTiO3 self-pumped phase-conjugate (PC) mirror in place of the usual mirrors is presented. The phase is shifted to produce a spatially uniform phase change uncancelled by a phase conjugator be- tween the two beams of an interferometer. The dc-light built-up PC reflectivity of -60 % is obtained for an incident angle of 14° to the crystal. The heterodyne beat signal associated with varying the pump-beams frequency of LD is measured up to -1 kHz. Experimental results of phase measurement with a four-stepping method are shown.
