some similar features with the

two-photon state generated from SPDC, yet it
also has some distinct characteristics. Coincidence photon-counting rate, which is
a significant nonclassical figure of merit of the two-photon state, has been shown
to depend heavily upon various experimental parameters. The dependence on the
ratio of the pump bandwidth to filter bandwidth is of practical importance, because
it serves as a guideline for optimizing the measurement of coincidence counts.
Single-photon counting rate has also been studied, and both fit to the experimental
data reasonably well . While in this chapter we are only concerned with parametric
fluorescence from a single pump pulse, the current theory can be readily extended
to include multiphoton-stat ...
