Effect of phase fluctuations on entanglement generation in a correlated emission laser with injected coherence

This proposal investigates the influence of the phase fluctuations on the time evolution of entanglement generation in a three-level correlated emission laser (CEL) with injected coherence. The atoms are injected in the cavity with an initial partial coherent superposition of the upper and lower levels. The corresponding phase φφ is considered to be randomly distributed around some fixed phase φ0φ0. The fluctuations in phase φφ modifies the coherence between the two corresponding atomic levels. Therefore, we observe strong influence of phase fluctuations on the entanglement generation using the injected coherence CEL system.
