Observation Of Multi-Raman Gain Resonances In Rubidium Vapor
CHINESE PHYSICS B(2016)
摘要
We present an experimental study of multi-Raman gain resonances in a hot rubidium vapor. The experiment is performed based on a high-efficiency four-wave mixing process due to the Raman-driven coherence in a double-L configuration. The Raman gain resonance for Rb-85 atoms under a bias magnetic field is shown to be split into five or six peaks, depending on the orientation of the magnetic field. The formed multi-Raman gain resonances have potential applications in measurement of magnetic fields and generation of multi-frequency correlated twin beams.
