    "abstract": "We obtain gain of the probe field at multiple frequencies in a closed\nthree-level V-type system using frequency modulated pump field. There is no\nassociated population inversion among the atomic states of the probe\ntransition. We describe both the steady-state and transient dynamics of this\nsystem. Under suitable conditions, the system exhibits large gain\nsimultaneously at series of frequencies far removed from resonance. Moreover,\nthe system can be tailored to exhibit multiple frequency regimes where the\nprobe experiences anomalous dispersion accompanied by negligible\ngain-absorption over a large bandwidth, a desirable feature for obtaining\nsuperluminal propagation of pulses with negligible distortion.",
