Abstract

Wide-angle, large space–bandwidth-product coherent image amplification with a flat spatial frequency response is demonstrated in photorefractive Bi₁₂SiO₂₀ crystals under nonstationary grating recording conditions. By utilizing large-divergence, mutually phase-conjugate pump beams provided by a self-pumped BaTiO₃ crystal, high-fidelity phase conjugation with high reflectivity in Bi₁₂SiO₂₀ is demonstrated.
