Abstract:We discuss the generation and evolution of entanglement in a four-level laser with a subthreshold nondegenerate parametric oscillator. The entanglement properties of the two-mode light generated by this scheme is studied. We show that the light produced by the present system is strongly entangled with time evolution. Especially, with the help of the parametric oscillator, the high intensity of the entangled light between the two-mode cavity can be achieved.
