In this article we study the squeezing and statistical properties of
the light produced
by a non-degenerate three-level laser, with the parametric amplifier .
With the aid of the master equation, we obtain stochastic
differential equations. Applying the solutions of the resulting
differential equations, we calculate the quadrature variance,the
mean and variance of the photon number ,the photon number
correlation . However, the
two-mode driving light has no effect on the squeezing properties of
the cavity modes. On the other hand, the parametric amplifier and
the thermal reservoir increase the mean and the variance of the
photon number. Furthermore, employing the same solutions, we also
obtain the anti normally ordered characteristic function defined in
the Heisenberg picture.
