Fig. 3

I-P characteristic of the detector under study in microsecond regime compared with previous results on nanosecond regime (with OPO1) for indentical repetition rate and similar output powers. I-P curve displays a predomining linear behavior, with a smaller quadratic contribution slightly arising. The inset shows the difference in term of photons temporal concentration between the two configuration leading to either a PASRH domination or a TPC domination
