We consider a three-level laser coupled to a two-mode thermal reservoir via a single port mirror. Applying the master equation, we study the effect of decoherence on the squeezing, entanglement, and statistical properties of a two-mode cavity light at a steady state. It turns out that the two-mode thermal reservoir substantially degrades the degree of squeezing and entanglement. However, it significantly enhances the mean number of the photon pairs and intensity difference.

级联三能级激光器中退相干腔光的压缩和纠缠特性

我们考虑通过单端口反射镜将三能级激光器耦合到双模储热器。应用主方程，我们研究了退相干对稳态下双模腔光的压缩，纠缠和统计特性的影响。事实证明，双模蓄热器大大降低了挤压和缠绕的程度。但是，它显着提高了光子对的平均数和强度差。
