Photorefractive crystals such as BaTiO3, SBN, BSO, and BGO are by far the most efficient materials for the generation of phase conjugate waves and the recording of holograms. In addition, self-pumped phase conjugation occurs in many of these crystals at relatively low laser power.1,2 These conjugators are by far the most convenient phase conjugate mirrors available. Recently, there have been several significant developments in mutually pumped phase conjugators (MPPCs). in these conjugators, two incident incoherent laser beams can pump each other to produce a pair of phase conjugate beams inside a photorefractive crystal. The spatial wavefronts of the beams are conjugated, and the temporal information is exchanged. The phase conjugation requires the simultaneous presence of both beams. Such conjugators were demonstrated experimentally using two incoherent laser beams in BaTiO3.3-5
