Using a model presented in reference [10, 11, 16], we estimated the average number of photon pairs μ at the crystal output to be 0.168 at the maximum pump power (195 mW), and 3 pairs event probability at the crystal ouput to be a fraction equal to 0.056 of the two pairs generation probability for this pump power.
