| 摘 要： | 为了研究钡原子的里德堡态,利用单光子共振简并四波混频测量了Ba原子的6s6p1P1能级,获得了不同实验条件下四波混频谱信号.结果发现:温度和入射激光强度对简并四波混频谱线的影响比较明显,而缓冲气体压强对简并四波混频谱线的影响较小,实验结果将对钡原子里德堡态的实验研究提供有益的参考.

| Abstract: | In order to study the Rydberg state of Barium atom,single photon resonant degenerate four-wave mixing(FWM)was used to measure the 6s6p1P1 energy level of Barium atom,and FWM specture signal under different experimental conditions were achieved.The results showed that the influence of temperature and laser intensity on FWM are relatively obvious but the buffer gas pressure is relatively poor.These results may serve as a useful reference in further research work on the Rydberg state of Barium atom. |
