Abstract:

A high resolution spectroscopic technique using a nonresonant RF field in a level crossing experiment is proposed. Absorption sidebands, originally observed by Townes and Merritt 1947, are analyzed using a quantum electrodynamic QED approach. A model is developed using the Heisenberg operator formalism and the adiabatic approximation to describe the atomic dynamics. Results agree with a dressed states approach and the original experiment. The model is extended to a three level atom to describe level crossings and quantum beats for linear and quadratic Stark shifted atoms. Expressions are developed to define level crossings conditions and estimate critical experimental parameters.
