Динамика заселенностей уровней и поляризации при двухфотонном резонансном переходе 1s-2s в атоме водорода (антиводорода) в поле фемтосекундного лазерного импульса
Maria V. Ryabinina, Leonid A. Melnikov
The dynamics of two-photon 1s↔2s transition in (anti)hydrogen atom in the field of femtosecond linearly polarized standing wave laser pulse is investigated. The density matrix equations for three levels 1s, 2s, and 2p were solved numerically out of frames of rotating wave approximation and perturbation approach. The coherent Rabi oscillation at different spatial points, velocity effect on level populations, saturation behavior of 2p-level population, and spectra of multiphoton resonances are demonstrated.
