Isolating spectral contributions from local field effects in an atomic vapor using two-quantum 2D FT optical spectroscopy

Katherine W. Stone, Keith Adam Nelson

Published Jan 1, 2010• 0 citations
Publisher

Abstract

Two-quantum 2D Fourier transform optical spectroscopy is used to separate the contributions of dipole-dipole interactions to the overall nonlinear optical response which isolates them from the atomic resonances in rubidium vapor that generated them.

Probing dipole–dipole interaction in a rubidium gas via double-quantum 2D spectroscopy

Feng Gao, Steven T. Cundiff, Hebin Li

We have implemented double-quantum 2D spectroscopy on a rubidium vapor and shown that this technique provides sensitive and background-free detection of the dipole-dipole interaction. The 2D spectra include signals from both individual atoms and interatomic interactions, allowing quantitative studies of the interaction. A theoretical model based on the optical Bloch equations is used to reproduce the experimental spectrum and confirm the origin of double-quantum signals.
