本文综述了先进的和未来的激光干涉仪引力波探测器的一些关键使能技术，这些技术必须将测试质量与尽可能低的光学和声学损失、高稳定性激光器和各种抑制噪声的技术相结合。本文第一节对测试质量的声学特性进行了综述。第二节综述了目前先进激光干涉仪的反射镜普遍使用的非晶态介质涂层技术，但低的声学损耗将是非常有利的。在Sect.3综述了大幅度降低热噪声的新一代晶态光学薄膜。实验质量的光学性质在第一节中进行了回顾。4，特别关注硅的性质，这是未来探测器的重要候选材料。本文第五节介绍了支撑所有先进和下一代激光干涉仪的极低噪声、高稳定性激光技术。
This paper reviews some of the key enabling technologies for advanced and future laser interferometer gravitational wave detectors, which must combine test masses with the lowest possible optical and acoustic losses, with high stability lasers and various techniques for suppressing noise. Sect. 1 of this paper presents a review of the acoustic properties of test masses. Sect. 2 reviews the technology of the amorphous dielectric coatings which are currently universally used for the mirrors in advanced laser interferometers, but for which lower acoustic loss would be very advantageous. In sect. 3 a new generation of crystalline optical coatings that offer a substantial reduction in thermal noise is reviewed. The optical properties of test masses are reviewed in sect. 4, with special focus on the properties of silicon, an important candidate material for future detectors. Sect. 5 of this paper presents the very low noise, high stability laser technology that underpins all advanced and next generation laser interferometers.
