When a trichromatic laser field is applied to a cavity optomechanical system within the single-photon strong-coupling regime, we find that the motion of mirror can evolve into a dark state such that the cavity field mode cannot absorb energy from the external field. Via tuning three components of the pumping field to be resonant to the carrier, red-sideband and blue-sideband transitions in the displaced representation respectively, the state of mirror motion can exhibit non-classical properties, such as that in the Lamb-Dicke limit, the state evolves into a squeezed coherent state, and beyond the limit, the state can become a squeezed non-Gaussian state.
当将三色激光场应用于单光子强耦合 regime 内的腔光机械系统时，我们发现镜子的运动可以演化为暗态，使得腔场模式无法从外部场吸收能量。通过分别将泵浦场的三个分量调谐为与位移表示中的载波、红边带和蓝边带跃迁共振，镜子运动的状态可以表现出非经典特性，例如在兰姆 - 迪克极限下，状态演化为压缩相干态，而超出该极限时，状态可以变为压缩非高斯态。
