Abstract
Four-wave mixing near resonance in an atomic vapor can pro-
duce 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 85Rb vapor and demonstrate the analytic modela??s utility
as an experimental diagnostic.
