    "abstract": "We report the measurement of the photons flux produced in parametric\ndown-conversion, performed in photon counting regime with actively quenched\nsilicon avalanche photodiodes as single photon detectors. Measurements are done\nwith the detector in a well defined geometrical and spectral situation. By\ncomparison of the experimental data with the theory, a value for the second\norder susceptibilities of the non linear crystal can be inferred.",
