Abstract:
In this research we have studied the squeezing, entanglement and statistical prop erties of the cavity light beams produced by a nondegenerate three-level laser with
a closed cavity and coupled to a two-mode vacuum reservoir via a single-port mir ror. We have carried out our analysis by putting the noise operators associated with
the vacuum reservoir in normal order. Applying the solutions of the equations of
evolution for the expectation values of the atomic operators, the interaction Hamil tonian and the quantum Langavin equations for the cavity mode operators, we have
calculated the mean and variance of the photon number as well as the quadrature
squeezing, photon and atom entanglement of the cavity light. We have found that
the mean photon number and its fluctuation, quadrature squeezing, and photon
entanglement within the laser cavity are enhanced by increasing the stimulated
emission decay constant. In addition, proper choice of the amplitude of the driv ing coherent light increases these non-classical features. The mean photon number
and its fluctuation also become more intense for large frequency interval. Moreover,
the squeezing and entanglement of the two-mode light are directly related and their
maximum strength is found to be 43%.
