    "abstract": "We investigate the propagation of a coherent probe light pulse through a\nthree-level atomic medium (in the $\\Lambda$--configuration) in the presence of\na pump laser under the conditions for gain without inversion. When the carrier\nfrequency of the probe pulse and the pump laser are in a Raman configuration,\nwe show that it is possible to amplify a slow propagating pulse. We also\nanalyze the regime in which the probe pulse is slightly detuned from resonance\nwhere we observe anomalous light propagation.",
