    "abstract": "The construction of a single photon source using gated parametric\nfluorescence is reported with the measurement results of the photon number\ndistribution. A beamlike twin-photon method is used in order to achieve high\ncollection efficiency. The estimated probability P(1) to find a single photon\nin a collimated output pulse is 26.5 % at a repetition rate of 10 kHz when the\neffective quantum efficiency of 27.4 % in the detection setup is compensated.",
