论文摘要
激光的频率稳定性受到最新频率参考中的热噪声的限制。进一步的改进需要在低温温度下运行。在这种情况下，我们研究了基于光纤的环形谐振器。我们的系统显示出一阶温度不敏感的点约为$ 3.55 $ K，远低于结晶硅。观察到的对振动的低敏感性（$ <5 \ cdot {10^{ - 11}}} \，\ text {m}^{ - 1}^{ - 1} \ text {s}^{2} $），温度（$ -22（$ -22（1）\ cdot {10^{ - 9}} $ { - 9}} $ { - 9}} $ （$ 4.2（2）\ cdot {10^{ - 11}} \，\ text {mbar}^{ - 2} $）使我们的方法有望实现未来的精确实验。
The frequency stability of lasers is limited by thermal noise in state-of-the-art frequency references. Further improvement requires operation at cryogenic temperature. In this context, we investigate a fiber-based ring resonator. Our system exhibits a first-order temperature-insensitive point around $3.55$ K, much lower than that of crystalline silicon. The observed low sensitivity with respect to vibrations ($<5\cdot{10^{-11}}\,\text{m}^{-1} \text{s}^{2}$), temperature ($-22(1)\cdot{10^{-9}}\,\text{K}^{-2}$) and pressure changes ($4.2(2)\cdot{10^{-11}}\,\text{mbar}^{-2}$) makes our approach promising for future precision experiments.
