The Relationship Between Collision-Assisted Zeeman and Hanle Resonances and Transverse Optical Pumping

Abstract

Four-wave light mixing experiments to study the phenomenon of collision-induced coherence were reported at two previous laser spectroscopy conferences [1,2]. In the meantime a full-length paper has reviewed the collision-induced Zeeman coherences [3]. More recently, the observation of collision-induced Hanle resonances in zero magnetic field has also been reported by us [4]. The connection of these collision-assisted Hanle resonances and transverse optical pumping was pointed out [5]. The language of optical pumping [6] was also employed by KOSTER et al. [7] to describe Hanle resonances in phase conjugate four-wave mixing experiments. It is the purpose of this note to elaborate on this relationship.and to discuss differences in the behavior of the collision-assisted four-wave-mixing signal for tuning near the D1 and D2 resonance lines, respectively.KeywordsPhase ConjugateTransverse PolarizationZero Magnetic FieldPhase Conjugate WaveFWHM WidthThese keywords were added by machine and not by the authors.
