    "abstract": "We study the interaction of a nearly resonant linearly polarized laser beam\nwith a cloud of cold cesium atoms in a high finesse optical cavity. We show\ntheoretically and experimentally that the cross-Kerr effect due to the\nsaturation of the optical transition produces quadrature squeezing on both the\nmean field and the orthogonally polarized vacuum mode. An interpretation of\nthis vacuum squeezing as polarization squeezing is given and a method for\nmeasuring quantum Stokes parameters for weak beams via a local oscillator is\ndeveloped.",
