用强度调制光对He-4（2 3S 1）亚稳原子进行光抽运。使用单模二极管泵浦的LNA激光器作为泵浦源，允许研究由光泵浦理论预测但尚未观察到的共振信号。在调制频率及其谐波下，在透射泵浦光束上检测到谐振。本文提出了这种方法在高灵敏度磁力仪中的应用。
He-4 (2 3S1) metastable atoms are optically pumped with intensity modulated light. The use of a single mode diode-pumped LNA laser as the pumping source, allows the study of resonance signals predicted by the optical pumping theory but not yet observed. Resonances are detected on the transmitted pumping beam at the modulation frequency and its harmonics. Application of this method to high sensitivity magnetometers is suggested.
