Photon Statistics of a Two-Level Atom inside an Optical Parametric Oscillator

C. Elliot Strimbu** and Perry Rice

We consider intensity-field correlation functions for a two-level atom in a degenerate optical parametric os-
cillator (OPO). Analytic results are obtained in the limit of weak driving fields using quantum trajectory
methods. We find large violations of inequalities satisfied by classical fields. We compare our results to those
of an ordinary OPO. We also calculate the second-order intensity correlation function for transmitted and
fluorescent light, as well as for cross correlations. Here we report large violations of inequalities for the intensity
cross-correlation functions in the weak field limit.
