10.12.06 - We have demonstrated cooling of a micromechanical resonance of 58 MHz from 300 K to 11 K using radiation pressure. The observed cooling is a manifestation of the effect of dynamical backaction, which occurs when the photon lifetime is comparable to the mechanical oscillation period. Extending this method to cryogenic temperatures, might enable reach yet lower temperatures...
