Superposed Coherent and Two Laser Light Beams

Abstract

In this paper, we have studied the squeezing and statistical properties of superposed three light beams. In order to carry out the analysis, we have obtained the superposition density operator along with the Q-functions, we have calculated the mean photon number, the photon number variance and the quadrature variance for the superposed three light beams. It has been found that the mean photon number and quadrature variances of the superposed three light beams are the sum of the mean photon numbers and quadrature variances of the separate light beams, respectively. The quadrature squeezing of the superposed three light beams is the average quadrature squeezing of the three light beams. In addition, the mean photon number and quadrature squeezing of the superposed three light beams increase with linear gain coefficient.
