Abstract
We investigate two-photon transitions and strong-field effects on Rydberg atoms using Autler- Townes splitting of electromagnetically-induced transparency resonances in rubidium 85 atoms. We first drive the one-photon 62S1/2 - 62P3/2 transition for a reference measurement of the electricfield in our experiments. We then measure Rabi frequencies for the two-photon 62S1/2 - 63S1/2 and 61D5/2 - 62D5/2 Rydberg transitions via Rydberg EIT-AT, over an electric field range up to 40 V/m. A Floquet analysis is used to model field-induced level-shifts and state-mixing effects present in the strongly driven quantum systems under consideration. Calculations are found to be in good agreement with experimental observations.Citation
