Abstract
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.
