We have demonstrated a double phase conjugator with orthogonal incident polarizations that generates both extraordinary and ordinary polarized conjugate waves simultaneously in the same photorefractive crystal, with its polarization state preserved. The e-conjugate waves are yielded by photorefractive backscattering in the crystal, and the o-conjugate waves take place due to the coupling of the incident e-waves and o-waves through circular photogalvanic effect.
