Paper Abstract

We report the construction of single photon source using gated parametric fluorescence with the measurement result of the photon number distribution. We succeeded to increase the probability P(1) to find a single photon in a pulse to 26.5%. The availability of the source at room temperature, its long life time, and its wavelength tunability may also be useful for quantum cryptography and photonic quantum computation.
