In this thesis, we have investigated the statistical and squeezing properties of thernlight produced by a two-mode subharmonic generating system in a cavity driven byrntwo-mode coherent light and coupled to two-mode thermal reservoir via a singleportrnmirror. Employing the master equation for the system under consideration,rnwe obtain c-number Langevin equations associated with the normal ordering andrndetermined correlation properties of the noise forces. The solutions of the resultingrndifferential equations are then used to calculate the mean and variance of thernphoton number of the cavity light. We have found that the variance of the photonrnnumber is gerater than the mean of the photon number and hence the photonrnstatistics of the cavity light mode is super-Poissonian. Moreover, applying the samernsolutions, we also obtained the antinormally-ordered characteristic function withrnthe aid of which the Q function is determined. In addition, the Q function is usedrnto calculate the photon number distribution for the cavity mode. Furthermore, wernobtain the variance of the plus and minus quadrature of the two-mode cavity lightrnproduced by the two-mode subharmonic generating system. It is found that therntwo-mode driving coherent light has no effect on the squeezing properties of therncavity mode and the squeezing occurs in the plus quadrature. Finally, we havernfound that at steady state and at thershold, there is a 50% maximum squeezing ofrnthe two-mode cavity light when the cavity is coupled to vacuum reservoir.
