Optical parametric fluorescence spectra in periodically poled media.
A theoretical method and an original numerical procedure to calculate the light spectra generated by optical parametric florescence (OPF) in a periodically polled medium is presented. This efficient procedure allows us to precisely study the generation in a periodically poled lithium niobate crystal. As an example, the evolution of the OPF spectra as a function of the pump frequency is presented as an animation. Furthermore, we show that OPF spectra can be generated when the pump frequency goes below the degeneracy.
