| 摘 要： | 使用具有中间态的双光子共振非简并四波混频(NFWM)测量了Ba原子J＝0和J＝2的偶宇称里德伯线系，与现代实验方法不同，本方法是纯光学的方法，其光路简单，检测的是相干光，而不是电子或离子信号.当用窄带宽的激光时，本技术对里德伯能级的窄光谱结构可以获得消多普勒的分辨率.关键词：四波混频里德伯态

| Abstract: | We have applied two-photon resonant nondegenerate four-wave mixing (NFWM) with a resonant intermediate state to measure the energy levels of the Ba even-parity J=0 and J=2 series. Differing from other experiment techniques, our method is a pure optical technique. Instead of detecting electrons or ions, the signal here is a coherent light. Two-photon resonant NFWM is a Doppler-free spectroscopy when the incident laser beams have narrow bandwidths. |
