What is the optimized coincidence counts per second expected for pairs of photons generated by SPDC on a ppktp crystal?

I would like to know the maximum rate of pairs of photons  that can be generated by SPDC (and detected) with a continuous wave laser (405 nm). The crystal used is a 1 cm long 10 um period PPKT...
