The Dynamics Of Two-level Laser

In this thesis, we study the quantum properties of the light generated by a two-levelrnlaser in which two-level atoms in a cavity coupled to a vacuum reservoir are pumpedrnto the top level at a rate of rca. We consider the case in which two-level atoms and therncavity mode are interacting with vacuum reservoir. Employing the Master equationrnfor the system under consideration, we obtained the quantum Langevin equations forrnthe cavity mode and atomic operators. Employing the solution of these equationsrnalong with the correlation properties of the noise operators, we calculate the meanrnand the variance of the photon number of the cavity light. We have found that thernvariance of the photon number is greater than the mean of the photon number andrnhence the photon statistics of the cavity light mode is super-Poissonian. Moreover,rnwe determine the quadrature variance and the power spectrum of the cavity light
