论文摘要
我们提出和分析了一个剖宫产光学时钟（CLOC），该光钟有可能在685 nm处的CS原子中使用禁止的光学转变在紧凑的外形中进行高性能和简单操作。 CS原子使用$λ_ {\ textrm m} = 803〜 \ textrm nm $的魔法陷阱波长被困在3D光学晶格中。为了降低对磁场的敏感性，原子在两个循环跃迁上的探测相等，但相反的磁移。时钟的操作只需要在685、803、852 nm处进行三个二极管激光器，并且与依赖碱性地球原子或单个捕获离子的其他高性能光学时钟相比，它可以简化。分析表明，量子噪声有限的稳定性为$ 8.4 \ times 10^{ - 16}/\sqrtτ$，并且使用逼真的系统参数在1个月时达到1 NS时正时不确定性的潜力。
We propose and analyze a Cesium lattice optical clock (CLOC) which has the potential for high performance and simple operation in a compact form factor using a forbidden optical transition in Cs atoms at 685 nm. Cs atoms are trapped in a 3D optical lattice using a magic trap wavelength of $λ_{\textrm m}=803~\textrm nm$. To reduce sensitivity to magnetic fields the atoms are probed on two cycling transitions with equal magnitude, but opposite magnetic shifts. Operation of the clock requires only three diode lasers at 685, 803, 852 nm and is simplified compared to other higher-performance optical clocks that rely on alkaline earth atoms or single trapped ions. Analysis shows a quantum noise limited stability of $8.4\times 10^{-16}/\sqrtτ$ and the potential for reaching 1 ns timing uncertainty at 1 month with realistic system parameters.
