Item Dynamics of coherently driven Nondegrnerate three-level Atom in open cavity(Addis Ababa University, 2014-05) Yeshiwas, Abinet; Kassahun, Fesseha (PhD)We have investigated the squeezing and statistical properties of the light cavity coupled to a vacuum reservoir via a single-port mirror. We carry out our analysis by considering the vacuum reservoir to be a noiseless physical entity and by applying the large-time approximation scheme to the quantum Langevin equations. We have found that the mean photon numbers of light modes and are the same in the absence of spontaneous emission and the mean photon number of light mode is greater than that of light mode in the presence of spontaneous emission. Our analysis also shows that mode is in general in chaotic state while mode is in a chaotic state under certain conditions. It is also found that the superposed light modes are in squeezed state with a maximum quadrature squeezing of 43% for = 0 and 46.5% for = 0.1 below the coherent vacuum state level
