Item Qyantum Analysis of Coherently Driven Three-Level Lasers(Addis Ababa University, 2001-06) Demissie, Driba; Kassahun, Fesseha (PhD)We present a detailed derivation of the equations of evolution for the reduced density operators (or the master equations) of coherently driven degenerate and nondegenerate three-level lasers. Employing these equations we investigate the squeezing and statistical properties of the light generated by both types of lasers. In both cases, we find that the linear gain coefficient and the strength of the driving radiation highly affects the squeezing and the statistical properties of the light
