Some of the most exciting experiments planned in the UK and internationally - from studying extreme light-matter interactions, to the exploitation of quantum technologies - are demanding unpreceded performance in mirror coating technology. Optical thin film coatings appear ubiquitously in the technology around us, however current available performances will not meet the requirements for, and will thus limit the exploitation from, many of these experiments. For example, emerging extreme light-matter experiments are now handling power densities an order of magnitude higher than those previously achieved. This includes major UK infrastructures, including the Central Laser Facility (CLF) and the Scottish Centre for the Application of Plasma-based Accelerators (SCAPA), in addition to partnership initiatives in Europe including the 850MEuro European funded Extreme Light Infrastructure (ELI). All these experiments will soon require laser damage threshold (LDT) performance in the highly reflective mirrors at a level not currently available. This proposal, for the first time, will seek to exploit advanced optical coating technologies, developed with the field of gravitational wave astronomy, for use in intense-light matter experiments. Moreover, the capabilities developed will significantly support existing activities within the Quantum Technologies for Fundamental Physics (QTFP) and the UK's continued effort in gravitational wave astronomy.

英国和国际上计划进行的一些最令人兴奋的实验——从研究极端的光与物质相互作用到量子技术的利用——都要求镜面涂层技术具有前所未有的性能。光学薄膜涂层在我们周围的技术中无处不在，但是当前可用的性能无法满足许多此类实验的要求，因此将限制其应用。例如，新兴的极端光物质实验现在处理的功率密度比以前达到的功率密度高一个数量级。这包括英国的主要基础设施，包括中央激光设施 (CLF) 和苏格兰等离子体加速器应用中心 (SCAPA)，以及欧洲的合作伙伴计划，包括 850MEuro 欧洲资助的极光基础设施 (ELI)。所有这些实验很快都需要高反射镜的激光损伤阈值（LDT）性能达到目前无法达到的水平。该提案将首次寻求利用引力波天文学领域开发的先进光学镀膜技术，用于强光物质实验。此外，所开发的能力将极大地支持基础物理量子技术（QTFP）内的现有活动以及英国在引力波天文学方面的持续努力。
