Relative intensity squeezing by four-wave mixing with loss: an analytic model and experimental diagnostic

Quantum Physics 2011-02-15 v2 Atomic Physics Optics

Abstract

Four-wave mixing near resonance in an atomic vapor can produce relative intensity squeezed light suitable for precision measurements beyond the shot-noise limit. We develop an analytic distributed gain/loss model to describe the competition of mixing and absorption through the non-linear medium. Using a novel matrix calculus, we present closed-form expressions for the degree of relative intensity squeezing produced by this system. We use these theoretical results to analyze experimentally measured squeezing from a 85^{85}Rb vapor and demonstrate the analytic model's utility as an experimental diagnostic.
