Theoretical Study of the Townes-Merritt Effect in Level Crossing Experiments
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. Keywords: Spectroscopy; Level crossings; Quantum beats; Absorption sidebands; Nonlinear optics; Quantum optics; Theses. (jhd)
