LARGE QUADRATURE SQUEEZING AT HIGH INTENSITIES

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