    "abstract": "We have measured -3.5 dB (-8.1 dB corrected for losses) relative intensity\nsqueezing between the probe and conjugate beams generated by stimulated,\nnondegenerate four-wave mixing in hot rubidium vapor. Unlike early observations\nof squeezing in atomic vapors based on saturation of a two-level system, our\nscheme uses a resonant nonlinearity based on ground-state coherences in a\nthree-level system. Since this scheme produces narrowband, squeezed light near\nan atomic resonance it is of interest for experiments involving cold atoms or\natomic ensembles.",
