摘要

我们展示了一种基于法布里-珀罗腔的可搬运超稳时钟激光系统,该腔采用晶态 Al0.92_{0.92}Ga0.08_{0.08}As/GaAs 镜面镀膜、熔融石英(FS)镜面基底以及 20~cm 长超低膨胀(ULE\textsuperscript{\textregistered})玻璃隔圈,其预测热噪声底在 1 秒平均时间下的修正阿伦偏差为 modσy=7×1017\mathrm{mod}\,\sigma_\mathrm{y} = 7 \times 10^{-17}。该腔为圆柱形,在十个点处安装。其分数频率对加速度在三个笛卡尔方向上的灵敏度测得分别为 2(1)×10122(1) \times 10^{-12}/(ms2^{-2})、3(3)×10123(3) \times 10^{-12}/(ms2^{-2}) 和 3(1)×10123(1) \times 10^{-12}/(ms2^{-2}),属于已发表可搬运系统中最低的加速度灵敏度。该激光系统的不稳定度低至 modσy=1.6×1016\mathrm{mod}\,\sigma_\mathrm{y} = 1.6 \times 10^{-16}
