Abstract

We have theoretically and experimentally studied Raman resonances in multi-level atoms (specifically ⁸⁵Rb). By varying the relative orientation of the magnetic field with respect to the propagation direction of the Raman fields, we have changed the spectrum to consist of five, six, or eleven peaks. However, the spectrum was not always an incoherent sum of the five and six peak spectra and was not always symmetric with respect to the magnetically insensitive transition (clock transition). Using Ramsey interference, we explored decoherence and noise sources in or system. We discuss potential application to magnetometry.
