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 levelenThree-level Atom in open cavityThesis
