Selective Strong-Field Enhancement and Suppression of Ionization with Short Laser Pulses

Optics 2016-07-06 v5 Atomic Physics

Abstract

We experimentally demonstrate robust selective excitation and attenuation of atomic Rydberg level populations in sodium vapor (Na I) using intense laser pulses in the strong field limit (>1012W/cm2> 10^{12} W/cm^{2}). The coherent control of the atomic population and related ionization channels is realized for intensities above the over-the-barrier ionization intensity. A qualitative model predicts that this strong field coherent control arises through the manifestation of a Freeman resonance.
