Abstract
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.
