摘要：

Using a single-channel active Raman gain medium, we show a 220 +/- 20 ns advance time for an optical pulse of tau(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.
