The bright Einstein-Podolsky-Rosen(EPR) beam (with quantum correlations between the quadrature-phase amplitudes of the spatially separated signals and the idler beams), and the bright two-mode quadrature squeezed light have been experimentally generated from a cw nondegenerate optical parametric amplifier (NOPA) injected by seed wave with degenerate frequency but orthogonal polarization.

In this paper, we present the analytical solution of the Fokker-Planck equation of non-degenerate optical parametric amplification(NOPA)for generation of squeezed light.

Optimum realization of the EPR paradox in the non-degenerate parametric amplification system;
