We have earlier described a detailed mechanism of self-pumped phase conjugation in a barium titanate crystal [1]. The proposed mechanism was motivated and supported by observations of light paths in the crystal, and differs in some respects from better-known previous explanations of similar phenomena [2]. Our model attaches particular significance to a proposed resonance between two opposite reflecting corners and to the simultaneous existence of a system of cooperating transmission and reflection gratings. We show the operation of the hypothesized system of gratings, as simulated by computer analysis. The results show points of agreement and disagreement with the actual behavior of the self-pumping crystal.
