Experimental Studies of a Strongly Driven Rabi Transition

Abstract
The response of a strongly driven Rabi transition, which is associated with a strongly driven two-level atom, is studied. Such a driven Rabi transition exhibits Mollow splitting including gain features, and the Mollow spectrum associated with the original transition is also altered. We demonstrate that driving the Rabi transition produces a new transition at its own Rabi frequency, which can be driven to exhibit further Mollow splitting. Our experimental results are in good agreement with theory based on doubly dressed states.
