Joint distributions of multimode stimulated parametric down-conversion and controllable nonclassical effects

摘要

Based on recent results (Perina and Krepelka 2006 Opt. Commun. 265 632) we derive and illustrate multimode joint photon-number distributions, integrated-intensity distributions, sum and difference distributions and conditional distributions for stimulated parametric down-conversion in the approximation of large degrees of freedom. The stimulated process can increase or decrease nonclassical effects from spontaneous processes and it can be used to control them.
