Abstract
We present the results of an experiment proving in principle that negative (anomalous) dispersive transparent media can be realized. The Ca-transition 4s2 1S0 → 4s4p 1P1 at λ = 423 nm was chosen to investigate the absorption and index of refraction spectra of a two-level system strongly driven at resonance. For the simultaneous high precision measurement of loss and phase shift imposed on a probe field during the interaction with a chopped Ca-atomic beam we used a novel spectrometer which is based on a phase modulated Mach-Zehnder interferometer. So far, a dispersion of ∂$-ω/n0 = -(3.1 ± 1.0) × 10-10/MHz accompanied by residual absorption of α0 = (0.125 ± 0.040)%/cm has been achieved. These values are compared to the requirements which have to be achieved for a certain application of negative dispersion without absorption, that is for a broadband high build-up cavity (white-light cavity).
