Based on the fanning effect self-pumped and mutually pumped phase conjugation is demonstrated in photorefractive BTO-crystals with applied electric ac-fields. We used fiber-like crystals that enable a long interaction region and high applied electric fields. We realized three kinds of phase conjugating mirrors, self-pumped, externally self-pumped, and mutually pumped. Experimental results are given characterizing the spatial and temporal behavior of the phase conjugated wave and the transmission (imaging) of intensity and phase patterns.
