Abstract

In current and future gravitational-wave detectors, thermal noise from mirror coatings limits the sensitivity of the detectors. To reduce the coating thermal noise, coatings with excellent optical and mechanical properties are needed. In this review, an overview of postdeposition coating treatments and the latest worldwide research activities on coatings with low mechanical loss and low optical absorption are reported. A brief overview of coating design optimization, including innovative solutions such as multimaterial coatings and nanolayers, is also discussed.

当前和未来引力波探测器镜面涂层的研究与发展
在当前和未来的引力波探测器中,来自镜面涂层的热噪声限制了探测器的灵敏度。为了降低涂层的热噪声,需要具有优异光学性能和力学性能的涂层。本文综述了沉积后涂层的处理方法,以及国内外低机械损耗、低光吸收涂层的最新研究进展。简要概述了涂层设计优化,包括创新的解决方案,如多材料涂层和纳米层,也进行了讨论。
