High-precision alkali-atom density measurement and control methods using light absorption for dual-beam SERF magnetometers
《Chinese Optics Letters》2024年第5期41-46,共6页刘子傲 陆吉玺 胡朝晖 李晓昱 闫一凡 詹迪 李建利 
The alkali-atom density measurement method based on light absorption is highly suitable for a spin-exchange relaxationfree(SERF)atomic magnetometer because of its high-precision measurement and complete nonmagnetic in...

Zero field optically pumped magnetometer with independent dual-mode operation被引量：1
《Chinese Optics Letters》2022年第8期18-23,共6页Shaowen Zhang Jixi Lu Ying Zhou Fei Lu Kaifeng Yin Di Zhan Yueyang Zhai Mao Ye 
This work was supported by the National Key R&D Program of China(No.2018YFB2002405);the National Natural Science Foundation of China(No.61903013).
We propose a dual-mode optically pumped magnetometer(OPM)that can flexibly switch between single-beam modulation mode and double-beam DC mode.Based on a 4 mm×4 mm×4 mm miniaturized vapor cell,the double-beam DC mode...

Ultra-narrow parametric magnetic resonances in a miniature vapor cell
《Chinese Optics Letters》2017年第7期1-3,共3页章雪挺 杨国卿 戴康 陈鹰 
supported by the National Natural Science Foundation of China(No.41006060);the Foundation of Electronic Science and Technology the Most Important Discipline of Zhejiang Province
Multi-photon parametric magnetic resonance in a miniature vapor cell is demonstrated. Much more multi-photon magnetic resonance can be observed when the radio frequency field becomes stronger. The linewidth of the n p...
