Abstract

We investigate the reduction of Rayleigh scattering in four-wave mixing due to photo-induced spatial redistribution of atoms in atomic vapors. The Rayleigh scattering from the pump beams in optical phase conjugation is a major source of noise, which affects the fidelity of the phase-conjugated image. In the blue-shifted operation, the atoms are driven toward the low-intensity regions of the standing-wave pattern, leading to a reduction of Rayleigh scattering. We also investigate the effect of saturation on the differential scattering cross section.
