Abstract

Degenerate four-wave mixing is one of the most attractive methods of forming squeezed states of light¹ In order to observe appreciable (~×2) squeezing of fluctuations in the optical field from one quadrature to the other, the effective reflectivity for the phase conjugate wave must be near unity if there is only a single pass through the nonlinear medium. This requires strong pump light and operation near saturation of a two-level system.
