Abstract The effect of the coherence properties of pumping and input radiations on parametric up conversion (PUC) is treated in this paper. It is shown here that the PUC depends essentially upon the coherence properties of the pumping radiation whilst it is hardly affected by the coherence properties of the input radiation. It has been found that for chaotic (Gaussian) pumping radiation with an extremely high degree of coherence the total conversion efficiency is one half of that for coherent (Poisson) pumping radiation, whilst for chaotic pumping radiation with a very low degree of coherence the PUC is much more effective. The influence of the coherence properties of pumping radiation upon the PUC is explained by the intermodal correlation effects in the nonlinear interaction.
