Harmonic generation of Li atoms in one- and two-photon Rabi-flopping regimes

Kobra Nasiri Avanaki, Dmitry A. Telnov, Shih‐I Chu

We present a comprehensive theoretical and computational study on harmonic generation (HG) of Li atoms in one- and two-photon Rabi-flopping regimes where the population transfer from the ground $2s$ state to the excited $2p$ , $3s$ , and $3d$ states is substantial. Our all-electron approach is based on the time-dependent density-functional theory and takes into account the polarization of the core and the dynamic response of the electrons to the laser field. We show that the population oscillations in the time domain with the Rabi frequency $\mathrm{\ensuremath{\Omega}}$ are reflected in the fine structure of the HG spectra in the frequency domain on the scale of $2\mathrm{\ensuremath{\Omega}}$. Our results also manifest that even finer structures of the harmonic peaks on the smaller frequency scale originate from the pulse-shape-related interference effects. These features are clearly seen in one-photon Rabi-flopping regime between the $2s$ and $2p$ states. The pattern in the HG spectra becomes more complex in the two-photon Rabi-flopping regime involving $3s$ and $3d$ states. Our findings can be used for developing coherent control methods for HG in the Rabi-flopping regime.We present a comprehensive theoretical and computational study on harmonic generation (HG) of Li atoms in one- and two-photon Rabi-flopping regimes where the population transfer from the ground $2s$ state to the excited $2p$, $3s$, and $3d$ states is substantial.
