The Output Light From A Three-level Laser And A Coherently Driven Cavity Mode

In this thesis we study the statistical and squeezing properties of the output light fromrna degenerate three-level laser and a coherently driven cavity mode coupled to a vacuumrnreservoir. Applying the propagator method [1], we first obtain the Q function for the cavityrncoherent light as well as the light generated by the three-level laser. We then determine thernQ function for the superposition of the two light beams. Applying the input-output relation,rnwe determine the Q function for the output light.rnEmploying the Q function for the output light, we have calculated the mean photonrnnumber, the variance of the photon number, the quadrature variance, and the squeezingrnspectrum. It is found that the mean photon number we have obtained is greater than thernmean photon number obtained using the Q function derived from a single master equationrnfor the cavity mode (i.e when the cavity coherent photons are interacting with the three-levelrnatoms). However, this interaction doesn’t affect the quadrature variance and the squeezingrnspectrum of the output light
