  abstract     = {{The coherent exciton-light coupling in pulse propagation experiments on the A-exciton resonance in bulk
CdSe is investigated over a broad intensity range. At low light intensities, polariton propagation beats due to
interference between excited states on both polariton branches are observed. In an intermediate intensity
regime, the temporal polariton beating is suppressed in consequence of exciton-exciton interaction. At the
highest light intensities, self-induced transmission and multiple pulse breakup are identified as a signature for
carrier density Rabi flopping. Exciton-phonon scattering is shown to gradually eliminate coherent nonlinear
propagation effects due to enhanced dephasing of the excitonic polarization. Calculations using the semiconductor
Maxwell-Bloch equations are in qualitative agreement with the experimental data.}},
