Abstract: We have analyzed the squeezing and statistical properties of the cavity light beam produced by a coherently driven degenerate three‐level laser with a degenerate parametric amplifier (DPA) in an open cavity and coupled to a vacuum reservoir via a single‐port mirror. 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 and the quantum Langevin equation for the cavity mode operator, the mean photon number and the quadrature squeezing of the cavity light are calculated. And a large part of the mean photon number is confined in a relatively small frequency interval. Furthermore, we also obtain the antinormally ordered characteristic function defined in the Heisenberg picture. With the aid of the resulting characteristic function, we determine the Q function which is then used to calculate the photon number distribution.
