    Dynamics of Degenerate Three-Level Laser
    (Addis Ababa University, 2016-02) Abebe, Tesfaye; Hirpo, Deribe (PhD)
    We analyze the quantum properties of the light generated by a three-level laser coupled to a vacuum reservoir. The three-level atoms available in the cavity are pumped from the bottom to the top level at a rate rda. Employing the pertinent master equation, we obtained the equation of evolution for cavity mode and atomic operators. Moreover, we have calculated the mean and variance of the photon number, the quadrature variance and the quadrature squeezing as well as the power spectrum for the cavity mode
