论文摘要
$^{\ mathrm {229m}} $ TH核时钟过渡的激光光谱对于将来的核时钟构造是必不可少的。此任务需要在真空紫外线中具有宽光谱覆盖的精确激光源。在这里，我们提出了一个基于腔体增强的第七谐波生成的可调真空粉状频率梳子。它的可调频谱涵盖了$^{\ Mathrm {229m}} $ th核时钟过渡的当前不确定性范围。
Laser spectroscopy of the $^{\mathrm{229m}}$Th nuclear clock transition is necessary for the future construction of a nuclear-based optical clock. Precision laser sources with broad spectral coverage in the vacuum ultraviolet are needed for this task. Here, we present a tunable vacuum-ultraviolet frequency comb based on cavity-enhanced seventh-harmonic generation. Its tunable spectrum covers the current uncertainty range of the $^{\mathrm{229m}}$Th nuclear clock transition.
