Optimal Photon Generation from Spontaneous Raman Processes in Cold Atoms
arXiv:1707.03353 · doi:10.1088/1367-2630/aaf3c5
Abstract
Spontaneous Raman processes in cold atoms have been widely used in the past decade for generating single photons. Here, we present a method to optimize their efficiencies for given atomic coherences and optical depths. We give a simple and complete recipe that can be used in present-day experiments, attaining near-optimal single photon emission while preserving the photon purity.
