Abstract :
We present a single-photon source based on cavity-enhanced parametric down-conversion with < 3 MHz linewidth and a brightness of 14000 counts/(s times mW times MHz). Measuring heralded single-photon statistics, we achieved a 100-fold suppression of two-photon events compared to a Poissonian source.
