Abstract
We presentatechniquefor frequency shifting scatteringinduced noiseon squeezed light beams, providing immunity from scattered light while preserving the squeezed states. Usinga500Hzpre and postsqueezing apparatus path length modulation, we show up to a 20 dB reduction in scattering induced noise while recovering squeezing measurement below the shot noise level. Such a technique offers immunity to spurious scattering sources without the need for optically lossy isolation optics.
