Large quadrature squeezing at high intensities

Abstract

The squeezing properties of a system characterized by large χ(2) and χ(3) nonlinear susceptibilities and injected classical fields for the two relevant modes are studied as a function of the output power. A large reduction of noise levels well above threshold has been found and a remarkable dependence of the maximum squeezing on the input power has been shown. The possibility of an implementation with state of the art technology is demonstrated, enabling a practical realization of a laserlike source with a high degree of squeezing at high intensities. © 1993 The American Physical Society.
