| 摘 要： | 研究了原子相干性在双通道间的转移效率与拉曼单光子失谐的关系。在冷原子四能级Tripod型系统中,首先利用EIT动力学过程将光信号存储在原子的一个记忆通道上。然后通过拉曼双光子过程,我们进行了原子记忆在两个通道间相干转移的研究,结果表明,在一定的拉曼光强下,原子相干性在双通道间的转移效率随着拉曼单光子失谐发生变化,最大的转移效率可达到94%。

| Abstract: | We studies the relationship between the efficiency of coherence transfer in two-channel and single-photon detuning of Raman laser. In a four-level atomic system, we store a coherent optical signal in an initial channel by using EIT technology. Then we implement coherence transfer between two memory channels, by Raman two-photon transition. The maximum efficiency of coherence transfer along with the function of the frequency detuning of Raman lasers is about 94%. |
