首次探测到的引力波 GW150914 和 GW151226 与恒星质量黑洞的合并有关，预示着观察宇宙的全新方式的开启。为了达到观测引力波所需的灵敏度，我们投入了数十年的开发，与 GW150914 相关的峰值应变为 10−21 水平。引力波探测器目前作为改进的迈克尔逊干涉仪运行，其中与高反射镜涂层相关的热噪声对当前和未来仪器的灵敏度设置了关键限制。本文概述了与引力波探测相关的镜面涂层的发展以及该领域未来发展的前景。
The first detections of gravitational waves, GW150914 and GW151226, were associated with the coalescence of stellar mass black holes, heralding the opening of an entirely new way to observe the Universe. Many decades of development were invested to achieve the sensitivities required to observe gravitational waves, with peak strains associated with GW150914 at the level of 10−21. Gravitational wave detectors currently operate as modified Michelson interferometers, where thermal noise associated with the highly reflective mirror coatings sets a critical limit to the sensitivity of current and future instruments. This article presents an overview of the mirror coating development relevant to gravitational wave detection and the prospective for future developments in the field.
