Abstract
We discussed the conditions for realizing maximum index of refraction without absorption of the light and analyzed the effect of the finite bandwidths of the probe and driving field on the index of refraction and the gain in a Raman-driven four-level system. We found that the maximum index of refraction with vanishing absorption can be achieved by changing the intensity of the driving field or changing the detuning between the frequency of the driving field and the resonant atomic transition. The finite bandwidths of the driving field and the probe field could destroy the coherence of atoms, decrease the gain and change the value of the index of refraction
