Second-generation gravitational wave detectors that will directly detect gravitational waves for the first time are currently being assembled. Their sensitivity will be limited by intrinsic thermal motion of the atoms in the mirror coatings and the quantum nature of the laser beams in the detectors. This project aims to develop new designs with the aim of circumventing these limitations and developing the ultra-sensitive optical metrology required to realise those designs. It is expected that the increased sensitivity of these third-generation detectors will allow more detailed measurement of the gravitational wave signals and provide unprecedented understanding of some of the most violent events in the universe.

首次直接探测引力波的第二代引力波探测器目前正在组装中。它们的灵敏度将受到反射镜涂层中原子的固有热运动和探测器中激光束的量子性质的限制。该项目旨在开发新设计，以规避这些限制，并开发实现这些设计所需的超灵敏光学计量。预计这些第三代探测器灵敏度的提高将能够对引力波信号进行更详细的测量，并对宇宙中一些最剧烈的事件提供前所未有的了解。
