Influence of frequency detuning on carrier-wave Rabi flop-related phenomena in the extreme nonlinear optics regime

In a simplified two-level atom or atomic-like system, resonantly interacting with laser, the so-called carrier-wave Rabi flop occurs accompanied by the occurrence of higher spectral components when the Rabi frequency is comparable with the exciting laser frequency [S. Hughes, Phys. Rev. Lett.81, 3363 (1998)]. Beyond resonance, the introduction of a small detuning does not play a negative role as expected, however, the spectral intensity versus detuning exhibits a Gaussian-like distribution pattern, i.e., there exists an optimal detuning value for the maximal spectral intensity. In addition, the propagation effect also shows an obvious influence, manifested as an obvious shift of this optimal detuning value.
