The Relationship between Light Storage Efficiency and Repumping Intensity in Cold Atom Medium

Zhang Zhi-yin

By using electromagnetically induced transparency(EIT),we realized the optical signal storage and release in 87 Rb cold atom medium.We have got the curve of storage efficiency as a function of the repumping intensity in cooling system.Experimental results showed that:the storage efficiency increases with the repumping intensity,when it increases from zero;if the repumping intensity exceeds a certain intensity,the storage efficiency begins to decrease.A simple analysis interpreted the relationship between storage efficiency and the repumping intensity.

The Investigation of Relationship Between Light Storage Efficiency and Coupling Intensity in Cold Atom Ensemble

Hai Wang

By using electromagnetically induced transparency(EIT) dynamics,we realized the storage and release of optical signals in 87Rb cold atoms,studied the relationship between the storage efficiency and the coupling intensity.Experimental results show that the storage efficiency increases with the coupling intensity in the situation of low coupling intensity.When the coupling beam exceeds certain intensity,the storage efficiency doesn′t increase any more.Then it runs down with the rise of coupling intensity.By analyzing the absorption and dispersion characteristics of light pulse propagating through cold atoms,we made a qualitative explanation of the changing trend of the storage efficiency with the coupling intensity changing.

Light manipulation by dual channel storage in ultra-cold Rydberg medium

Xue-Dong Tian, Zi-Jiao Jing, Feng-Zhen Lv +2 more

We investigate the light propagation dynamics in ultra-cold Rydberg medium with inverted-Y configuration based on the superatom theory. It is viable to store light information in two types of atomic spin coherence (trivial spin coherence and Rydberg spin coherence), which makes the system a prospective platform for versatile light manipulation. A normal feature is to realize efficient light storage with simultaneous resonant control fields applied. An intriguing feature is to split light into two beams with different intensities and statistical properties if the control fields are applied separately. The beam of light retrieved from the Rydberg spin coherence is severely attenuated and shows anti-bunching character accompanied by the cooperative optical nonlinearity. Moreover, generation and manipulation of beating signal are achievable by applying the non-resonant control fields.
