With the aid of the master equation, we obtain stochastic differential equations. Applying the solutions of the resulting differential equations, we calculate the quadrature variance, the squeezing spectrum , the mean and variance of the photon number sum and difference. For a linear gain coefficient of 75 and for a cavity damping constant of 0.8, the maximum intracavity squeezing is found at steady state and at threshold to be 64%enA Nondegenerate Three- Level LaserA Nondegenerate Three- Level Laser with the Cavity modes driven by Coherent LightThesis
