We propose an optomechanically-induced-transparency cooling scheme to achieve ground state cooling of mechanical motion without the resolved sideband condition in a pure optomechanical system with two mechanical modes coupled to the same optical cavity mode. We show that ground state cooling is achievable for sideband resolution ωm/κ as low as~0.003. This provides a new route for quantum manipulation of massive macroscopic devices and high-precision measurements. 关键词：机械模式透明度冷却基态量子诱导谐振器光学机械系统
