Quantum Analysis of Degenerate Three-Level Laser

Abstract

We have studied the squeezing and statistical properties of the light produced by degenerate three level lasers. In order to carry out the analysis, we have obtained the c-number Langevin equations associated with the normal order using the pertinent master equations. Applying the Q-functions for degenerate three-level laser, we have determined the mean and variance of the photon number as well as the photon number distribution for degenerate three-level laser. It has been found that the mean photon number and quadrature squeezing increase with linear gain coefficient.
