A near-white-noise input–output formalism is developed that does not require white-noise assumptions. In particular, correlation formulas for outputs are developed, which enables account to be taken of reflections of near-white-noise inputs. The methods are applied to the inhibition of atomic phase decays by squeezed light from a degenerate parametric amplifier incident upon a two-level atom, and modifications from previous work carried out in the extreme-white-noise limit are computed.
