The temporal evolution of double phase-conjugate mirrors (DPCM's) in photorefractive materials such as BaTiO3:Co:Fe is studied by use of the plane-wave expansion method. The buildup time of DPCM and its conjugation fidelity are compared with those of photorefractive materials with a single-center transport. Numerical simulations show that one can decrease the threshold value of the coupling strength required for the DPCM operation with a high conjugation fidelity by doping the BaTiO3 crystals weakly with Co in comparison with undoped crystals.
