摘　　要：It has recently been shown that correlated spontaneous emission lasers （CEL） exhibit transient entanglement in the linear regime. Here we re-examine the quantum correlations in two-photon CEL and explore the saturation effects on continuous variable entanglement. It is shown that the steady state entanglement is obtainable in the weak or moderate saturation regime, while is washed out in the deep saturation regime.It has recently been shown that correlated spontaneous emission lasers （CEL） exhibit transient entanglement in the linear regime.
