    "abstract": "Employing the quantum Hamiltonian describing the interaction of two-mode\nlight (signal-idler modes) generated by a nondegenerate parametric oscillator\n(NDPO) with two uncorrelated squeezed vacuum reservoirs (USVR), we derive the\nmaster equation. The corresponding Fokker-Planck equation for the Q-function is\nthen solved employing a propagator method developed in Ref. \\cite{1}. Making\nuse of this Q-function, we calculate the quadrature fluctuations of the optical\nsystem. From these results we infer that the signal-idler modes are in squeezed\nstates and the squeezing occurs in the first quadrature. When the NDPO operates\nbelow threshold we show that, for a large squeezing parameter, a squeezing\namounting to a noise suppression approaching 100% below the vacuum level in the\nfirst quadrature can be achieved.",
