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. |
