    "abstract": "We describe an experiment in which we have used a cold damping feedback\nmechanism to reduce the thermal noise of a mirror around its mechanical\nresonance frequency. The monitoring of the brownian motion of the mirror allows\nto apply an additional viscous force without any thermal fluctuations\nassociated. This scheme has been experimentally implemented with the radiation\npressure of an intensity-modulated laser beam. Large noise reductions, up to 30\ndB, have been obtained. We have also checked the mechanical response of the\ncold damped mirror, and monitored its transient evolution between the cooled\nregime and the room temperature equilibrium. A simple theoretical model allows\nto fully explain the experimental results. A possible application to the active\ncooling of the violin modes in a gravitational-wave interferometer is\ndiscussed.",
