摘要:

在几十赫兹到几百赫兹的频段内,涂层布朗噪声是所有地面引力波探测器的主要噪声项。降低这类噪声对于提升这些仪器的可探测距离、最终使其达到量子极限而言是必不可少的。实现这一目标有多种可行策略,其中层厚优化是最简单的方案,既能实现显著的噪声降低,所面临的技术挑战也有限。实验结果证实了相关基础理论的准确性,以及该设计的稳健性。

英文摘要:

Coating Brownian noise is the dominant noise term, in a frequency band from a few tens to a few hundreds Hz, for all Earth-bound detectors of gravitational waves. Minimizing such noise is mandatory to increase the visibility distance of these instruments, and eventually reach their quantum limit. Several strategies are possible to achieve this goal. Layer thickness optimization is the simplest option, yielding a sensible noise reduction with limited technological challenges. Experimental results confirm the accuracy of the underlying theory, and the robustness of the design.
