Abstract
We have experimentally investigated the resonant optical response of a partially excited high-density atomic potassium vapor under conditions where local-field effects strongly influence the response. We have measured the excitation dependence of the Lorentz local-field shift, and found it to be in excellent agreement with theoretical predictions.
