Abstract
Using degenerate four-wave mixing in a Fe:LiNbO3 0.04-wt. % crystal and incremental recording, we have realized phase conjugation of light emitted by a fiber tip (of a near-field microscope) alternately placed at two close positions near the crystal surface. We observe with the near-field microscope that the phase-conjugated light forms two subwavelength-sized spots near the surface; the spots are elongated in the direction of the crystal optical axis. It is demonstrated that phase-conjugated light spots formed 240 nm apart in the direction perpendicular to the crystal optical axis can still be resolved.
