    "abstract": "Pulse propagation is considered in an inhomogeneously broadened medium of\nthree-level atoms in a V-configuration, dressed by a counter-propagating pump\npulse. A significant signal slowdown is demonstrated in this of the three\nfrequency windows of a reduced absorption and a steep normal dispersion, which\nis due to a cross-over resonance. Particular properties of the group index in\nthe vicinity of such a resonance are demonstrated in the case of closely spaced\nupper levels.",
