Gravitational-wave detectors such as Virgo and the laser interferometric gravitational-wave observatory (LIGO) use a long-baseline Michelson interferometer with Fabry-Perot cavities in the arms to search for gravitational waves. The symmetry between the two Fabry-Perot cavities is crucial to reduce the interferometer's sensitivity to the laser amplitude and frequency noise. To this purpose, the transmittance of the mirrors in both cavities should be as close as possible. This paper describes the realization and the characterization of the first twin large low-loss mirrors with transmissions differing by less than 0.01%.
像处女座引力波探测器和激光干涉引力波天文台（LIGO）这样的引力波探测器，使用带有法布里 - 珀罗腔的长基线迈克尔逊干涉仪来搜寻引力波。两个法布里 - 珀罗腔之间的对称性对于降低干涉仪对激光幅度和频率噪声的敏感度至关重要。为此，两个腔中镜子的透过率应尽可能接近。本文描述了首批透射率差异小于0.01%的双大型低损耗镜子的实现与特性。
