    "abstract": "In this paper we study the nondegenerate optical parametric oscillator with\ninjected signal, both analytically and numerically. We develop a perturbation\napproach which allows us to find approximate analytical solutions, starting\nfrom the full equations of motion in the positive P-representation. We\ndemonstrate the regimes of validity of our approximations via comparison with\nthe full stochastic results. We and that, with reasonably low levels of\ninjected signal, the system allows for demonstrations of quantum entanglement\nand the Einstein-Podolsky-Rosen paradox. In contrast to the normal optical\nparametric oscillator operating below threshold, these features are\ndemonstrated with relatively intense felds.",
