Two optical configurations for generating two self-pumped phase-conjugated waves from two signal laser beams transporting different information were presented: one in which the two signal laser beams were directed at two opposite faces [($\bar{1}00$) and (100)] of the crystal and the other in which both beams were directed at the same (100) face. Using a barium titanate (BaTiO3) single crystal as a self-pumped phase-conjugated mirror, the generation conditions of two discrete self-pumped phase-conjugated waves of high quality with reduced interference were investigated. Successfully self-pumped phase-conjugated images were observed to be more readily achievable by changing the incident beam power than by changing the incident position onto a single face.
