    "abstract": "We describe an experiment in which the quadratures of the position of an\nharmonically-bound mirror are observed at the attometer level. We have studied\nthe Brownian motion of the mirror, both in the free regime and in the\ncold-damped regime when an external viscous force is applied by radiation\npressure. We have also studied the thermal-noise squeezing when the external\nforce is parametrically modulated. We have observed both the 50% theoretical\nlimit of squeezing at low gain and the parametric oscillation of the mirror for\na large gain.",
