The continuous variable quadripartite entanglement properties of the output fields by the coupled intracavity parametric downconversions processes are analyzed theoretically. In the above-threshold region, it shows that the four output lights are multicolored entangled beams in separable locations with four-mode amplitude quadratures correlation and relative phase quadratures correlation.
