| Abstract: | We report the measurement of the photons flux produced in parametric down-conversion, performed in photon counting regime
with actively quenched silicon avalanche photodiodes as single photon detectors. Measurements are done with the detector in
a well defined geometrical and spectral situation. By comparison of the experimental data with the theory, a value for the
second order susceptibilities of the non linear crystal can be inferred.
