Ultrafast and selective coherent population transfer in four-level atoms by a single frequency chirped few-cycle pulse
arXiv:1303.0206 · doi:10.1103/PhysRevA.88.033823
Abstract
We report and propose a simple scheme to achieve the ultrafast and selective population transfer in four-level atoms by utilizing a single frequency chirped few-cycle pulse. It is demonstrated that the almost complete population may be transferred to the preselected state of atoms just by manipulating the so called chirp offset parameter. The robustness of the scheme against the variation of laser pulse parameters is also investigated. The proposed scheme may also be useful for the selective population transfer in molecules.
