Two-mode Coherent And Squeezed Light

Employing c-number Langevin equations and taking into considerations the correlationrnproperties of the noise forces, we obtained the antinormally-ordered characteristic func-rntion, and with the aid of this result, we have determined the Q-function for a two-rnmode cavity light. Upon the pertinent Q-function, we have calculated the mean andrnthe normally-ordered variance of the photon numbers sum and di erence, the quadraturernvariance, the photon number correlation and the quadrature squeezing
