我们从实验和理论上分析了循环光辐射压力激励下的光学谐振腔内的机械振荡。由此产生的射频腔振动（声子模式）引起入射的连续波（cw）输入泵浦光束的调制。此外，随着连续泵浦功率的增加，从谐振器耦合的泵浦功率中观察到从正弦调制到随机振荡的演变。研究了随抽运功率的时间演变，并与理论相符。除了在量子光学力学中的应用，目前的工作表明，辐射压力引起的效应可以建立一个实际的限制光学二氧化硅微腔的小型化。
We analyze experimentally and theoretically mechanical oscillation within an optical cavity stimulated by the pressure of circulating optical radiation. The resulting radio frequency cavity vibrations (phonon mode) cause modulation of the incident, continuous-wave (cw) input pump beam. Furthermore, with increasing cw pump power, an evolution from sinusoidal modulation to random oscillations is observed in the pump power coupled from the resonator. The temporal evolution with pump power is studied, and agreement was found with theory. In addition to applications in quantum optomechanics, the present work suggests that radiation-pressure-induced effects can establish a practical limit for the miniaturization of optical silica microcavities.
