我们分析了一个高精细光学腔的非线性动力学，其中一个反射镜安装在一个灵活的机械元件。我们发现，这个系统是由一系列的动态吸引子，这是由于锁相之间的机械振荡的镜子和振铃的光强度在腔中。我们开发了一个分析理论，绘制出参数空间中的吸引子图，推导出系统的慢振幅动力学，包括热波动，并提出了一个计划，利用动态多稳定性的测量小位移。
We analyze the nonlinear dynamics of a high-finesse optical cavity in which one mirror is mounted on a flexible mechanical element. We find that this system is governed by an array of dynamical attractors, which arise from phase locking between the mechanical oscillations of the mirror and the ringing of the light intensity in the cavity. We develop an analytical theory to map out the diagram of attractors in parameter space, derive the slow amplitude dynamics of the system, including thermal fluctuations, and suggest a scheme for exploiting the dynamical multistability in the measurement of small displacements.
