【 摘 要 】

Studies of near-resonant dressing of cold strontium gases and BECs held in an optical dipole trap (ODT) with the 303S1Rydberg state reveal that, even when well detuned from resonance, such dressing can lead to a rapid decrease in the ground state atom population in the trap. This decrease is attributed to Rydberg atom excitation, which can trigger direct escape from the trap and population of long-lived metastable states.
