利用腔内增强辐射压力，实现了58 MHz微机械谐振器从室温到11K的冷却。光学共振的失谐泵浦允许相对于导致机械振荡器模式冷却的红移边带，增强蓝移的运动边带(由振子的布朗运动引起)。已报道的冷却机制是辐射压力引起的动态反作用的一种表现。这些结果是实现机械振荡器基态冷却的重要一步。
Cooling of a 58 MHz micromechanical resonator from room temperature to 11 K is demonstrated using cavity enhanced radiation pressure. Detuned pumping of an optical resonance allows enhancement of the blueshifted motional sideband (caused by the oscillator's Brownian motion) with respect to the redshifted sideband leading to cooling of the mechanical oscillator mode. The reported cooling mechanism is a manifestation of the effect of radiation pressure induced dynamical backaction. These results constitute an important step towards achieving ground state cooling of a mechanical oscillator.
