摘要：

Cold damping feedback mechanism was described for the reduction of thermal noise of a mirror around its mechanical resonance frequency. Additional viscous force, without any extra thermal fluctuation, was applied by monitoring the Brownian motion of the mirror. The mechanical response of the cold damped mirror was checked. A theoretical model was developed to describe the experimental results.
