详细
Polarization spectra of a two-level system in a polychromatic field were obtained in two cases: using the rotating wave approximation and without using this approximation. The obtained spectra were compared using two indicators: the average deviation across the entire frequency range and the deviation at the transition frequency. Both indicators allow quantitative assessment of the distortion in polarization spectra introduced by the application of the rotating wave approximation. The dependencies of the above indicators on key model parameters were obtained – on the central frequency, detuning, and spectral width of the applied polychromatic field. The obtained dependencies allow evaluating the applicability limits of the rotating wave approximation for a given level of acceptable distortions in the polarization spectrum.
