Stimulated Photorefractive Backscatter Leading to Six-Wave Mixing and Phase Conjugation in Iron Doped Lithium Niobate (Preprint)
Abstract
Oblique incidence of a 532 nm pump on LiNbO3:Fe, nominally propagating along the +c axis, produces six waves through two-wave coupling (self diffraction) and four-wave mixing (parametric diffraction). One of these waves, the stimulated photorefractive backscatter, contains the self-phase conjugate. The dynamics of six-wave mixing and their dependence on crystal parameters and angle of incidence are analyzed. A novel order analysis of the interaction equations provides further insight into experimental observations. The quality of the backscatter is evaluated through image restoration, interference experiments, and visibility measurement. Reduction of two-wave coupling may significantly improve the quality of the self-phase conjugate.
