| 摘 要： | 基于铯原子6S1/2 -6P3/2 -8S1/2的阶梯型能级系统,对室温下铯原子气室中的电磁感应透明(EIT)谱进行了研究.由于探测光的频率锁定于基态6S1/2(F=3)到中间态6P3/2的超精细跃迁线上,耦合光在中间态6P3/2和激发态8S1/2之间扫描,得到的EIT谱具有平坦的背景,提高了光谱的精度.理论上,采用了一个多能级的EIT模型,将其计算结果与所观察的实验现象进行了比较,二者符合得比较好.

| Abstract: | Based on the cesium 6S1/2 -6P3/2 -8S1/2 ladder-type system, electromagnetically-induced transparency (EIT) is further investigated in a room-temperature vapor cell. When the probe laser is locked to one of the hyperfine transitions between the ground state 6S1/2 (F=3) and the intermediate state 6P3/2 while the coupling laser scans the transition between the intermediate state 6P3/2 and the excited state 8S1/2, the EIT spectrum has a flat background improving the spectral resolution. The theoretically calculated EIT spectral profiles from a multi-level ladder-type model are consistent well with the obtained experimental phenomena. |
