We investigate the creation of entangled states of bright light beams obeying the condition of strong Einstein-Podolsky-Rosen-like paradox criterion in time-modulated quantum dissipative dynamics. Having in view the generation of these states we propose a non-degenerate optical parametric oscillator(NOPO) driven by an amplitude-modulated pump field. We develop semi-classical and quantum theories of this device for all operational regimes concluding that, contrary to ordinary NOPO, the continuous-variable entanglement becomes approximately perfect for high level of modulation. Our analytical results are in well agreement with numerical simulations.
