Abstract

In the five-level K-type atomic system, by using another control field to couple the excited level of the coupling transition to the sixth higher excited level, a six-level atomic system is constructed. In this system, the multiple electromagnetically induced two-photon transparency has been investigated. What is more, if choosing the parameters of the control fields properly the triple transparency window will reduce to a double one which means that the multiple electromagnetically induced two-photon transparency can be manipulated in this system. The physical interpretation of these phenomena is given in terms of the dressed states and the dark states.

Local Control of Two-Photon Absorption in a Six-Level Atomic System by Using a Coherent Perturbation Field

Jia Wen-Zhi, Shun-Jin Wang

If a coherent perturbation field is used to couple the excited level of the coupling transition in the five-level K-type atom with another higher excited level, the two-photon electromagnetically induced transparency can be locally modulated by altering the parameters of the additional perturbation field. With different detunings of the coherent perturbation field, the absorption peak or transparency window with sharp and high-contrast spectral feature can be generated in the two-photon absorption spectrum. The physical interpretation of these phenomena is given in terms of the dressed states.

The absorption properties in an inverted-tripod scheme atomic system driven by the coherent fields are investigated by means of the semiclassical theory.The result obtained by means of numerical method indicates that by adjusting the Rabi frequencies of the coherent fields,there appear triple,double,single electromagnetically induced transparency(EIT).In the triple EIT,the location of transparent windows can be controlled by adjusting the detunings for the coherent fields,and changes continuously,i.e.there exist a series of continuous frequencies for the probe field propagating in an atomic medium without absorption in a certain range.Finally,the explanations of these phenomena are given by using the dressed states.

Multiple electromagnetically induced transparency in a quasi-Λ type four-level atomic system

Xiangwei Wang, Xiangyang Zhang

Using density matrix eqution, the absorption and dispersion properties of a A-type four-level system driven by coherent fields are investigated. The result obtained by means of numerical method indicates that by adjusting the intensity of Rabi frequencies of the coherent field in the steady state, three, double or single electromagnetically induced transparency (EIT) can appear explicitly in this system. And the explanations of these phenomena are given by using the dressed states. In the three EIT, the location of transparent windows can be manipulated by controlling the detuning of the driving field. What's more, it is also found that the medium shows a large refractive index at each transparency window, and the group velocity of the probe laser can be enhanced.
