论文摘要
无定形涂层中的热噪声是广泛的精确实验（例如重力波探测器（GWD））的限制。 GWD的镜子由沉积在基板上的多层介电材料层组成：堆栈由高折射率高的层制成，并与低折射率的层交织在一起。目标是获得高反射率和低热噪声。在本文中，我们报告了离子光束含氟化铝（ALF $ _3 $）薄膜的光学和机械性能，这些薄膜是已知涂层材料中最低折射率之一，我们在当前和未来的GWD中讨论了它们的应用。
Thermal noise in amorphous coatings is a limitation for a wide range of precision experiments such as gravitational-wave detectors (GWDs). Mirrors for GWDs are composed of multiple thin layers of dielectric materials deposited on a substrate: the stack is made of layers with a high refractive index interleaved with layers of a low refractive index. The goal is to obtain high reflectivity and low thermal noise. In this paper we report on the optical and mechanical properties of ion-beam-sputtered aluminium fluoride (AlF$_3$) thin films which have one of the lowest refractive index among the known coating materials and we discuss their application in current and future GWDs.
