中文摘要：

基于Duan-Lukin-Cirac-Zoller（DLCZ）方案,在时域上研究了扩散诱导的Ramsey压窄.以87Rb热原子系综为研究对象,观测到缓冲气体,激光束尺寸和镀石蜡Rb池均可以导致Ramsey压窄现象.实验结果和文献中重复相互作用模型预期的一致.

英文摘要：

Experimental study of diffusion-induced Ramsey narrowing in time domain based on Duan-Lukin-Cirac-Zoller protocol is reported.We take a thermal 87Rb atomic ensemble as an example,observe that these factors,such as buffer gas,laser beam radius and paraffin coated cell,can result in diffusion-induced Ramsey narrowing.The experimental results agree with the predictions of a repeated interaction model.
