Abstract
Applying the propagator method discussed in J. Math. Phys. 33 (1992) 2179, we calculate
the Q function of the cavity coherent light and the signal mode produced by a degenerate
subharmonic generator. We then determine the superposition of these two light beams.
Employing the input-output relation, we obtain the Q function of the output light. With
the aid of the resulting Q function, the squeezing and statistical properties of the output
light are analyzed. It is found that the coherently driven cavity mode has no e ect on the
quadrature variance of the output light. However, it enhances the mean photon number
of the output light.
