We analyze a general approach for suppressing inhomogeneous broadening of atomic transitions and thereby increasing the strength of the interaction between the atomic system and near-resonant light. The key idea is to compensate for the frequency shift due to the broadening process by using an intense laser to produce an equal and opposite Stark shift.
