Influence of EIT coherence on laser phase-noise to intensity-noise conversion

ORAL

Abstract

Laser phase-noise can induce intensity-noise through interactions with atoms. We report an experimental study of the influence of EIT coherence in Rb vapor on this noise conversion process. Enhancement of the intensity-noise is observed as the EIT coherence is varied via two-photon Raman detuning. We attribute this enhancement to the correlation of phase fluctuations created in EIT. Potential implications for CPT atomic clocks will be discussed.
