项目摘要

Optical coatings are key components within almost all technology that surrounds us from our glasses to cameras. Extreme-performance coatings are used in optical atomic clocks and gravitaitonal-wave detectors which are the most sensitive clocks and distance meters ever built. Optical coatings are also essential for industrial applications in photonics, particularly for miniaturisation of laser diode devices and for increasing the laser damage threshold.Optical coatings consist of alternating layers of materials with different refractive indices and are only a few micrometers thick. Their performance is determined by the amount of light scattered and absorbed inside the coating and by their thermal noises caused by the Brownian motion of the atoms. Optical coatings can be manufactured out of a large variety of materials, such as tantalum oxide, silica, and amorphous silicon. However, the ultimate properties of the coatings depend both on the intrinsic properties of these materials and on the manufacturing process. Therefore, it is essential to have a robust experiment to test novel coatings for precision instruments.We propose to build an internationally-leading facility to directly measure the properties of novel optical coatings. This proposal emanates from two recent findings. First, the MIT LIGO group found that coating samples can be measured in one week using a multimode optical resonator. Second, groups in academia in the UK, USA, and Germany developed a new class of promising extreme-performance coatings for applications in precision measurements. The proposed centre is a crucial step in commercial manufacturing of high-quality coatings since we need to experimentally explore the whole parameter space of coating production, such as deposition rate, doping materials, and annealing temperature.The key idea of the proposed experiment is to embed a coating sample in the optical resonator and measure its properties using three co-resonating beams. This setup will make all displacement noises common to these beams, except for the coating thermal noises. The main advantage of the proposed facility is that it can test one coating sample per week at the telecom laser wavelength and has the potential to be the first in the world working with extreme-performance coatings in this parameter space. The centre will be able to directly measure coating samples for future optical atomic clocks, next generation of gravitational-wave detectors, fundamental physics experiments and for the commercial applications.
光学涂层是几乎所有技术中从眼镜到相机周围的所有技术中的关键组件。极端性能的涂料用于光原子时钟和引力塔纳尔波探测器,这些探测器是有史以来最敏感的时钟和距离仪表。光学涂层对于光子学中的工业应用也至关重要,特别是对于激光二极管设备的微型化和增加激光损伤阈值。光涂层由具有不同折射率指数的交替材料层组成,并且只有几微米厚。它们的性能取决于散射的光的量并在涂层内部吸收的量以及由原子的布朗运动引起的热噪声。光学涂层可以由多种材料制成,例如氧化诱m,二氧化硅和无定形硅。但是,涂料的最终特性既取决于这些材料的内在特性和制造过程。因此,必须进行强大的实验来测试新颖的涂层以进行精密仪器。我们建议建立一个国际领先的设施,以直接测量新型光学涂层的性质。该提议源于最近的两个发现。首先,MIT Ligo组发现可以使用多模光谐振器在一周内测量涂料样品。其次,英国,美国和德国学术界的小组为精确测量中的应用开发了一类新的有希望的极端性能涂料。所提出的中心是高质量涂层商业制造的关键步骤,因为我们需要在实验中探索涂料生产的整个参数空间,例如沉积速率,掺杂材料和退火温度。拟议实验的关键思想是将涂层样品嵌入光学谐振器中并使用三个共旋转束进行测量其性能。除了涂层热声音外,这种设置将使这些光束共有的所有位移噪声。提议的设施的主要优点是,它可以在电信激光波长每周测试一个涂料样品,并且有可能成为世界上第一个在此参数空间中使用极端性能的涂料。该中心将能够直接测量未来光学原子时钟,下一代重力波探测器,基本物理实验和商业应用的涂料样品。
