光学频率基准的紧凑性、稳健性和自主性是移动系统在地面和空间可靠运行的先决条件。我们提出了一个独立的即插即用光学频率基准装置，基于780 nm的Rb的D2跃迁的频率调制光谱。在按下单个按钮后，基于微集成激光-光学工作台的手工尺寸激光模块，在[J.opt.SoC。上午好。B38,1885(2021)10.1364/JOSAB.420875]，完全自主工作，产生6 mW的稳频光，在1 S时的相对频率不稳定性为1.4×10-12，在10 5 S平均时间时低于10-11。我们描述了器件的设计，研究了热特性对输出频率的影响，并通过贝叶斯优化器改变调制参数证明了短期频率稳定度的改善。
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. B38, 1885 (2021)10.1364/JOSAB.420875], works fully autonomous and generates 6 mW of frequency stabilized light with a relative frequency instability of 1.4×10-12 at 1 s and below 10-11 at 105 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.
