High-fidelity image amplification and phase conjugation in photorefractive Bi(12)SiO(20) crystals.
Wide-angle, large space-bandwidth-product coherent image amplification with a flat spatial frequency response is demonstrated in photorefractive Bi(12)SiO(20) crystals under nonstationary grating recording conditions. By utilizing large-divergence, mutually phase-conjugate pump beams provided by a self-pumped BaTiO(3) crystal, high-fidelity phase conjugation with high reflectivity in Bi(12)SiO(20) is demonstrated.
