论文摘要

当激光器表现出较大的间歇性频率跳跃时,使用高技能腔开发了一种实验方法,用于稳健的频率稳定。这是通过在频率锁定范围增加的原子束中使用来自多普勒荧光光谱的额外缓慢反馈信号来完成的。结果,稳定且狭窄的宽度556 nm激光器保持频率锁定状态超过一周,并有助于更准确地评估YB光学晶格时钟。此外,在没有任何振动隔离表的情况下,在不振动点上支持参考光腔,从而使激光设置更加简单和紧凑。

An experimental method is developed for the robust frequency stabilization using a high-finesse cavity when the laser exhibits large intermittent frequency jumps. This is accomplished by applying an additional slow feedback signal from Doppler-free fluorescence spectroscopy in an atomic beam with increased frequency locking range. As a result, a stable and narrow-linewidth 556 nm laser maintains the frequency lock status for more than a week, and contributes to more accurate evaluation of the Yb optical lattice clock. In addition, the reference optical cavity is supported at vibration-insensitive points without any vibration isolation table, making the laser setup more simple and compact.
