Using a single-channel active Raman gain medium, we show a 220{+-}20 ns advance time for an optical pulse of {tau}{sub FWHM}=15.4 {mu}s propagating through a 10 cm 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.
