DEGENERATE SQUEEZED LIGHT WITH COHERENT AND THERMAL LIGHTS

Abstract

The squeezing and statistical properties of the light produced by the degenerate threelevel laser whose cavity contains nonlinear crystal generating squeezed light and the cavity mode is driven by coherent light and coupled to thermal reservoir have been studied and applying c-number expectation value of the cavity mode variables associated with the normal ordering at steady state, the quadrature variances, squeezing and the mean and variance of the photon number have been determined. It is found that the effect of the thermal reservoir is to increase the mean photon number and decreases the quadrature squeezing. The presence of nonlinear crystal in the cavity increases both the mean photon number and the quadrature squeezing.
