摘要：

We experimentally demonstrate robust selective excitation and attenuation of atomic Rydberg level populations in sodium vapor (NaI) using intense laser pulses in the strong-field limit (>10(12)W/cm(2)). Coherent control of the atomic population and related ionization channels is realized for intensities above the over-the-barrier ionization intensity. Moreover, atomic excitation selectivity and high ionization yield are simultaneously achieved without the need to tailor the spectral phase of the laser. A qualitative model confirms that this strong-field coherent control arises through the manifestation of a Freeman resonance.
