Cold atoms from a magneto-optic trap have been used as a nonlinear () 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.
PACS: 32.80.Pj – Optical cooling of atoms; trapping / 42.50.Lc – Quantum fluctuations, quantum noise, and quantum jumps / 42.65.Pc – Optical bistability, multistability, and switching
