We theoretically investigate the effect of phase fluctuations on correlated photons resulting from nondegenerate three-level atoms under the cavity radiation. The photon statistics, photon number correlation, and entanglement properties of the system have been calculated employing the dynamical equation of the system. It is shown that, for the sub-Poissonian photon statistics, the degree of correlation increases with the atomic pumping rate, and the entanglement varies with phase fluctuations, rather than with the atomic pumping rate. The proposed system is well suitable for the quantum information processing.
