rather, observed that the degree of entanglement increases with time for all parameters under consideration. This outcome suggests that a better degree of entanglement would be expected at steady state which is believed to be an important aspect in practical utilization of the system. It can readily be seen from Fig. \[fig5\] that when the atoms are pumped externally with strong coherent radiation, the entanglement appears to decrease with the rate of dephasing. Moreover, one can observe from Fig. \[fig6\] that the nature of the degree of entanglement does not display much change from what is imparted in Fig. \[fig5\] except decrement in the effect of the rate of phase fluctuation slightly. In order to show the dependence of the evolution of the entanglement on the phase fluctuation in depth, $V_{s}$ is plotted against $time$ for different values of $\theta$. Relatively spaced values of $\theta$ are chosen so that the modification in the evolution of the entanglement be evident from the plots. As can easily be noticeable from Fig. \[fig7\], the degree of entanglement increases with the phase fluctuation. This is in a complete agreement with a recent observation that in case when there is a strong external driving the
