Squeezing with cold atoms

Cold atoms from a magneto-optic trap have been used as a nonlinear ($\chi^{(3)}$) medium in a nearly resonant cavity. Squeezing in a probe beam passing through the cavity was demonstrated. The measured noise reduction is 40% for free atoms and 20% for weakly trapped atoms.
