Abstract

We have demonstrated enhanced nondegenerate four-wave mixing by use of a resonant probe in a double-Λ system consisting of an optically dense spectral hole-burning solid. The observed probe diffraction efficiency is ∼16% in amplitude at 6 K, which is higher than for an off-resonant probe in a Λ-type scheme. We have also observed two-photon coherence line narrowing, which has potential application to high-resolution spectroscopy.
