Abstract:
We demonstrate a method for time gating the standard heralded cw spontaneous parametric downconverted single-photon source by using pulsed pumping of an optical parametric oscillator below threshold. The narrow bandwidth, high purity, high spectral brightness, and pseudodeterministic character make the source highly suitable for light-atom interfaces with atomic memories.
