Abstract
We examine phase conjugation in liquid suspensions of microparticles in the saturation limit. If the polarizations of the pump waves are orthogonal, new states should appear discontinuously in a pairwise fashion which are stable at the bifurcation point. These states correspond to different intensities of the conjugate and amplified probe waves. Analysis indicates that this effect should be experimentally accessible in the microwave region utilizing 10-μm microspheres.
