Abstract
When narrowband probe radiation traveling through a bulk material is tuned to a resonance transition from the ground state of the material, the radiation experiences strong attenuation and dispersion. Recent theoretical1 and experimental2,3 work has demonstrated that this attenuation can be almost completely eliminated by the addition of a strong coherent coupling radiation field coupling a third state to the upper state of the resonance transition. In effect, a destructive quantum interference blocks the excitation of the atom from its ground state and renders the atom transparent. We term this effect “electromagnetically induced transparency.”
