Entanglement Quantification of Correlated Photons Generated by Three-Level Laser with Parametric Amplifier and Coupled to a Two-Mode Vacuum Reservoir

Figure 1

Schematic representation of nondegenerate three-level laser with a nonlinear crystal (NLC) and coupled to a two-mode vacuum reservoir. Here, , considered to be real and constant, is proportional to the amplitude of the pump mode that drives the NLC, represents the rate at which the atoms are injected into the cavity, and is cavity damping constant, and it is assumed the same for both transitions.
