Abstract
A semiderivative method, which consists of illumination of a photorefractive medium with a weak beam that is incoherent with the interacting beams, is described for stabilization of unstable steady states in photorefractive phase conjugators, such as an externally pumped four-wave mixer, a semilinear self-pumped phase conjugator, and a double phase conjugator.
