On solving the resulting FokkerPlanck equation employing the method of evaluating the propagatOl" method discussed in Ref. [1], we have obtained the Q-function for a single-mode DSV driven by a single-mode coherent light and damped by a single-mode thermal reservoir. Finally, we have calculated using this Q-function the quadrature fluctuations, the mean photon number, the variance of the photon number and the photon number distribution. We have also carried out the same analysis for a two-mode DSV driven by a two-mode coherent light and damped by a two-mode thermal reservoirenCoherently Driven SqueezedThesis
