    A Nondegenerate Three- Level Laser with the Cavity modes driven by Coherent Light
    (Addis Ababa University, 2007-07) Mekonen, Wubshet; Kassahun, Fesseha (PhD)
    In this thesis we study the squeezing and statistical properties of the light produced by a nondegenerate three-level laser, with the cavity modes driven by coherent light. 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%
