用微波调制的半导体激光观测^（87）Rb超精细能级的相干共振

Observation of Hyperfine Coherence Resonances in ￣(87)Rb with Microwave Modulated Semiconductor Laser

用微波调制的半导体激光泵浦８７Ｒｂ汽泡室原子，直接观察到其基态超精细能级间△ｍＦ＝０、±１和±２的能级相干共振信号，其中Ｏ－Ｏ（Ｆ＝２，ｍＦ＝０）能级相干共振信号可用作原子钟的参考标准．

Hyperfine coherence resonances with △mF= 0, ±1, ±2 are observed in 87Rb vapor optically pumped with a microwave modulated semiconductor laser. The O - O(F= 2, mF = 0) hyperfine coherence resonance may be used as a reference of the atomic clock.
