  In this paper, we extend the results of an earlier paper in which we had
demonstrated the limitations of the notion of non-resonant multiphoton
ionization, in the exploration of photon statistics effects in non-linear
processes. Through the quantitative analysis of specific realistic processes,
we provide the connection to conditions of intensity and pulse duration
necessary in relevant experiments, including a recent seminal experiment
demonstrating the effect of superbunching found in squeezed radiation.
