摘要
超窄线宽稳频激光在精密测量、精密光谱学、原子频标等领域起着至关重要的作用,其频率稳定性依赖于作为参考的超稳腔的性能。水平放置的超稳腔对外界振动非常敏感,往往与其理论设计存在量级差异,使得振动噪声成为限制超稳腔稳定性的重要因素。本文以圆柱形水平参考腔为例,基于有限元分析方法,提出了7.3×10-12/g(g=9.81 m·s^(-2))超低振动敏感度腔的设计方案,分析了加工和装配过程中影响振动敏感度的各项误差因素,并提出了相应的解决方案。本研究方法对于其他形状的超稳腔的振动不敏感设计同样适用,将来可用于各类精密测量实验中。
Ultra-narrow linewidth frequency-stabilized lasers play a crucial role in the fields of precision measurement,precision spectroscopy,atomic frequency standard and other fields,and its frequency stability depends on the performance of the reference ultra-stable cavity.The horizontally placed ultra-stable cavity is highly sensitive to external vibrations.Usually,there is a magnitude difference between actual vibration sensitivity and its theoretical design,which makes vibration noise an important factor limiting the stability of the ultra-stable cavity.This paper takes a cylindrical horizontal cavity as an example and proposes a cavity design with a low vibration-sensitive of 7.3×10-12/g(g=9.81 m·s^(-2))based on the finite element analysis method.Error factors affecting vibration sensitivity during processing and assembly are analyzed,and the corresponding solutions are proposed.It is indicated that the method proposed in this work is also applicable to vibration-insensitive designs of other shapes of ultra-stable cavities,and can be used in various precision measurement experiments in the future.
