布拉金斯基的理论工作预测，辐射压力能够将法布里 - 珀罗谐振腔的机械本征模式（镜子的本征模式）与其光学模式耦合，导致参量振荡不稳定性。这种机制的特征是机械镜子本征模式的再生性机械振荡。我们最近在一个超高Q值的光学微腔中观测到了机械模式的激发。在此，我们对这种效应进行了详细的实验分析，并证明辐射压力是所观测到的机械振荡的激发机制。
The theoretical work of Braginsky predicted that radiation pressure can couple the mechanical, mirror eigenmodes of a Fabry-Perot resonator to its optical modes, leading to a parametric oscillation instability. This regime is characterized by regenerative mechanical oscillation of the mechanical mirror eigenmodes. We have recently observed the excitation of mechanical modes in an ultrahigh Q optical microcavity. Here, we present a detailed experimental analysis of this effect and demonstrate that radiation pressure is the excitation mechanism of the observed mechanical oscillations.
