中文摘要：
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.
英文摘要：
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.
