Item Quantum Analysis of Coherently Prepared Degenerate and Nondegenerate Three-Level Lasers(Addis Ababa University, 2001-06) Abayneh Mesfin; Kassahun Fesseha (PhD)We present a detailed derivation of the master equations for coherently prepared degenerate and nondegenerate three-level lasers coupled to vacuum reservoirs. Employing these equations we analyze the squeezing properties of the cavity radiation and the output radiation. We find that under certain conditions squeezed light can be generated. The same equations are also used to study the photon statistics for the two systems. We see that the distribution functions have the same form as the one for the signal mode from parametric oscillators
