Abstract

We analyzed the mutual influence of simultaneous processes of second harmonic generation and parametric down conversion within the framework of a fully quantum approach. The effect of depletion of quantum pumping has been revealed. The effect of establishing a balance between the processes under consideration and achieving an equilibrium number of photons in the field modes is found. The generation of a strongly entangled two-mode field is demonstrated.
