Abstract

Optical noise in two-level atoms is of fundamental interest as it limits the accuracy of atomic clocks and the amount of squeezing that can be obtained in atomic systems. It also contributes to momentum diffusion in laser cooling experiments. In this work, we measure phase-dependent optical noise spectra for the radiation emitted by long-lived coherently driven two-level atoms in an atomic beam. Bloch vector projection noise, spontaneous emission noise, and phase-dependent Poisson noise contribute to the measured noise spectra. The experiment is interpreted using a decay-free Bloch vector model.
