Abstract

We propose and demonstrate a new configuration of mutual- coherent-pumped phase conjugation with Ce:BaTiO₃. Two coherent beams are incident into a crystal and overlap inside the crystal. The two input beams undergo stimulated photorefractive backscatterings in separated regions, in which their corresponding phase conjugations are generated. Then the four waves in the crystal undergo four-wave mixing. The intensity ratio as well as the interference modulation of the two phase conjugations is characterized as a function of the intensity ratio of the input beams. The phase conjugator exhibits a large intensity dynamic range. We theoretically analyze the modulation transfer function of the mutual-coherent-pumped phase conjugator with Ce:BaTiO₃. The theoretical analysis is in agreement with the experimental results.
