| Abstract: | We present a theoretical and experimental study of the spatio-temporal properties of the spontaneous parametric emission generated
in a type I LBO crystal around degeneracy. The number of quasi-phase-matched modes is shown to be equal to the number of spatio-temporal
degrees of freedom of the image that can be parametrically amplified. From this number, we demonstrate the possibility of
predicting the total number of photons generated by parametric fluorescence. Correlation is observed between spatial intensity
fluctuations corresponding to pairs of signal-idler modes.
