摘要:

光学频率基准的紧凑性、鲁棒性和自主性是地面和空间移动系统可靠运行的先决条件。我们提出了一个独立的即插即用的光学频率基准设备的基础上的频率调制光谱的D2跃迁在780 nm的铷。在按下单个按钮之后,基于[J. Opt. Soc. Am. B 38,1885-1891(2021)],完全自主工作,并产生6 mW的频率稳定光,其相对频率不稳定性在1 s时为1.4e-12,在1 e5 s平均时间时低于1 e-11。我们描述了该设备的设计,调查的热特性影响的输出频率,并证明短期的频率稳定性改善贝叶斯优化器改变调制参数。

英文摘要:

Compactness, robustness and autonomy of optical frequency references are prerequisites for reliable operation in mobile systems, on ground as well as in space. We present a standalone plug and play optical frequency reference device based on frequency modulation spectroscopy of the D2-transition in rubidium at 780 nm. After a single button press the hand-sized laser module, based on the micro-integrated laser-optical bench described in [J. Opt. Soc. Am. B 38, 1885-1891 (2021)], works fully autonomous and generates 6 mW of frequency stabilized light with a relative frequency instability of 1.4e-12 at 1 s and below 1e-11 at 1e5 s averaging time. We describe the design of the device, investigate the thermal characteristics affecting the output frequency and demonstrate short-term frequency stability improvement by a Bayesian optimizer varying the modulation parameters.
