title = "Superluminal propagation of an optical pulse in a Doppler-broadened three- state single-channel active Raman gain medium",
abstract = " Using a single-channel active Raman gain medium, we show a 220±20ns advance time for an optical pulse of τ FWHM =15.4 μ s propagating through a 10cm medium, a lead time that is comparable to what was reported previously using a two-mode pump field. In addition, we have verified experimentally all the features associated with this single-channel Raman gain system. ",
