Analysis of quantum correlation for two-Mode light Produced by non-Degenerate three level laser

Abstract

We studied the various quantum correlations for the input and output two-mode light generated by non-degenerate three level laser coupled to vacuum reservoir. First we have constructed the Hamiltonian for our system. Applying this Hamiltonian, we have obtained the pertinent master equation which have been used to obtain the steady state solutions of the equation of evolution of the expectation values of the cavity mode operators. Applying the resultingsteadystatesolutions,wehavestudiedthequadraturevariance,entanglement,discord and steering of the radiation. The obtained results showed that the quantum correlations of the radiation generated by non degenerate three level laser increase with linear gain coefficient (A), for small values of population inversion (η). On the other hand applying the input-out put relation we have also shown that the quantum correlation of the cavity mode isgreaterthantheoutputmode.
