We investigate the interaction of strong single-cycle THz-pulses with a coherent excitonic polarization. The initial bleaching is superimposed by a splitting of the 1 s exciton resonance and eventually is accompanied by the emergence of side-bands on both the high and low energy sides of the former resonance. A quantum-mechanical many-body analysis associates these observations with the transition from excitationinduced bleaching and the regime of excitonic Rabi flopping to multi-THz-photon ionization and hence the population of states with high orbital quantum numbers.
