摘要
文章介绍了在磁光阱制备的Rb85冷原子团中通过特定时序的光场进行四波混频的实验研究,我们观察到了混频光强度的空间分布,简要讨论了三束作用光场的频率和光强对混频光产生的影响。时序调制下的四波混频实验为利用冷原子系综制备非经典关联光子对提供了基础。
Generation of non-classical correlated photon pairs via spontaneous four-wave-mixing (FWM) in cold atomic ensembles is a promising field in quantum information process. In this paper we report on the realization of stimulated four-wave-mixing based on the cold 85Rb atoms, which is prepared in a magneticoptieal trap. We have observed the spatial distribution of the output parametric field, and briefly discussed how the intensities and frequencies of the three input beams affect this process. Temporal sequences modulation is used to control the interaction for the subsequent work of generating the non-classical correlated photon pairs.
