Abstract
We show that stimulated two-wave mixing is the origin of phase conjugate fields in self-pumped photorefractive mirrors. We predict that the bulk photovoltaic effect gives rise to an intensity-dependent frequency shift in the phase conjugate field and is the physical origin for the occurrence of beam fanning.
