Quantum Dynamics of V Laser Coupled to Squeezed Vacuum Reservoir

Abstract

The quantum dynamics of light produced by a two-mode v laser coupled to squeezed vacuum reservoir have been analyzed with the aid of the solutions of c-number Langevin equations associated with the normal order along with the correlation relation. We determined the quadrature variances and photon statistics of the cavity modes. The results showed that the light produced by the system under consideration is in squeezed state and the degree of squeezing increases with squeeze parameter(r). Furthermore, it was found that the mean and variance of photon number increases with the linear gain coefficient. In addition, we have calculated the variance of the sum of EPR-operators with the aid of the solutions of c-number Langevin equation and Duan et al. criteria. The results showed that the entanglement of the cavity mode increases with squeeze parameter(r) and decreases with linear gain coefficient.
