We have demonstrated experimentally the simultaneous self-conjugation of extraordinarily and ordinarily polarized light waves (λ = 514 nm), with the polarization state preserved, in a Ce:BaTiO3 crystal. Conjugate o waves originate from coupling between o and e waves by means of a circular photogalvanic effect. The conjugator also takes advantage of the Ce:BaTiO3 crystal, for which it is easy to generate an extraordinary conjugate beam by photorefractive backscattering. This beam of light is necessary for double phase conjugation.
