    Review of Coherently Driven Resonance Light of Degenerate Three Level Laser
    (Addis Ababa University, 2018-12-04) Entehabu, Gebresenbet; Hirpo, Deribe (PhD)
    We analyze a degenerate three-level laser driven by coherent light and coupled to a vacuum reservoir via a port-mirror. Employing the solutions of the c-number Langevin equations we have determined the mean photon number, variance of the photon number and quadrature variance of the cavity radiation.The mean photon number would be zero when there is no driving light and all atoms are initially in the bottom level, and the most intense light is produced when all atoms are initially in the upper level. We observed that the more atoms are injected into the cavity at a time, the more the degree of the squeezing of the cavity radiation would be.
