Interest in lossless nonlinearities has focussed on the dispersive properties of \ensuremathΛ systems under conditions of electromagnetically induced transparency (EIT). We generalize the \ensuremathΛ system by introducing further degenerate states to realize a ``chain \ensuremathΛ'' atom where multiple coupling of the probe field significantly enhances the intensity-dependent dispersion without compromising the EIT condition.
