论文摘要
使用碱金属原子在真空环境中包含的rydberg辅助原子测量值，用于在频率<$ <$ <$ <$ <$的频率上检测外部电场（电子场），这是由于低频电子野生型筛选效果而受到质量较大的挑战。我们报告了一个非常缓慢的电子场筛选现象，其时间比例为$ \ sim $ second，在rubidium（rb）蒸气池中，由单晶蓝宝石制成。使用这种蓝宝石制造的RB蒸气电池，具有光学诱导的内部偏置电子场，我们展示了基于蒸气的低频原子电器测量值，从而对E-Field的强度响应线性响应。受给定的实验条件的限制，该证明原子电表使用11毫米$^3 $的活性体积，并提供光谱底噪声底部约$ 0.34 $（mv/m）/$ \ sqrt {\ rm hz} $和3 db的3 dB低切割频率左右的770 Hz左右。这项工作调查了以前很少研究的基于蒸气的原子电剂的制度，这可能会实现更多利用原子电子电场传感技术的应用。
Rydberg-assisted atomic electrometry using alkali-metal atoms contained inside a vacuum environment for detecting external electric fields (E-fields) at frequencies $<$ a few kHz has been quite challenging due to the low-frequency E-field screening effect that is caused by the alkali-metal atoms adsorbed on the inner surface of the container. We report a very slow E-field screening phenomenon with a time scale up to $\sim$ second on a rubidium (Rb) vapor cell that is made of monocrystalline sapphire. Using this sapphire-made Rb vapor cell with optically induced, internal bias E-field, we demonstrate vapor-cell-based, low-frequency atomic electrometry that responds to the E-field strength linearly. Limited by the given experimental conditions, this demonstrated atomic electrometer uses an active volume of 11 mm$^3$ and delivers a spectral noise floor around $0.34$ (mV/m)/$\sqrt{\rm Hz}$ and the 3-dB low cut-off frequency around 770 Hz inside the vapor cell. This work investigates a regime of vapor-cell-based atomic electrometry that was seldom studied before, which may enable more applications that utilize atomic E-field sensing technology.
