    "abstract": "In a three-level atomic system coupled by two equal-amplitude laser fields\nwith a frequency separation 2$\\delta$, a weak probe field exhibits a\nmultiple-peaked absorption spectrum with a constant peak separation $\\delta$.\nThe corresponding probe dispersion exhibits steep normal dispersion near the\nminimum absorption between the multiple absorption peaks, which leads to\nsimultaneous slow group velocities for probe photons at multiple frequencies\nseparated by $\\delta$. We report an experimental study in such a\nbichromatically coupled three-level $\\Lambda$ system in cold $^{87}$Rb atoms.\nThe multiple-peaked probe absorption spectra under various experimental\nconditions have been observed and compared with the theoretical calculations.",
