论文摘要
参数不稳定性（PI）是一种现象，它是由于激光腔的光学和声学模式之间的共振相互作用而引起的。这在引力波干涉仪中是有问题的，在重力波干涉仪中，高腔内功率和低机械损耗镜悬架系统创造了一个环境，其中将在没有干预的情况下发生三种模式PI。我们展示了一种用于实时成像的技术，以实现PI的光学模式的幅度和相位，从而产生了这种现象的第一个图像，该图像可能构成了未来检测器的主动控制策略的一部分。
Parametric Instability (PI) is a phenomenon that results from resonant interactions between optical and acoustic modes of a laser cavity. This is problematic in gravitational wave interferometers where the high intra-cavity power and low mechanical loss mirror suspension systems create an environment where three mode PI will occur without intervention. We demonstrate a technique for real time imaging of the amplitude and phase of the optical modes of PI yielding the first ever images of this phenomenon which could form part of active control strategies for future detectors.
