Spatial and temporal properties of parametric fluorescence around degeneracy in a type I LBO crystal

  • F. DevauxEmail author

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 quasiphase-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.

    The center of these circular profiles has been precisely determined thanks to the almost perfect axial symmetry of the fluctuations, using an algorithm originally designed for determining the axis of turbofan engines that present the same symmetry: L.
