    "abstract": "Using a single channel active Raman gain medium we show a $(220\\pm 20)$ns\nadvance time for an optical pulse of $\\tau_{FWHM}=15.4 \\mu$s propagating\nthrough a 10 cm medium, a lead time that is comparable to what was reported\npreviously. In addition, we have verified experimentally all the features\nassociated with this single channel Raman gain system. Our results show that\nthe reported gain-assisted superluminal propagation should not be attributed to\nthe interference between the two frequencies of the pump field.",
