Abstract
In this paper, we present a detailed analysis of the dynamics of the cavity radiation of a coherentlypumped correlated-emission laser. We find that the phase fluctuations and dephasing significantly affect the two-mode squeezing, entanglement, and the radiation intensity. The results obtained show that almost perfectly entangled light can be generated while the rate of dephasing and phase fluctuations are kept high in the case, where the atoms are initially prepared in a possible maximum coherence. Although we find that varying the phase fluctuations and dephasing enhances the degrees of squeezing. Since the intensity and quantum features can be readily enhanced, this system is expected to be a viable source of a strong robust entangled and squeezed light under various conditions. In addition, we show that the Mandel Q-factor for this system is definitely greater than zero. This ensures that the radiation generated demonstrates super-Poissonian photon statistics, while exhibiting nonclassical properties such as squeezing and entanglement. Detailed analysis shows that this behavior would not be affected in an essential way by changing the rate of dephasing and phase fluctuations.
