Two-Dimensional Electronic Spectroscopy for Three-Level Atoms with Electromagnetically Induced Transparency

Two-dimensional electronic spectroscopy (2DES) has high spectral resolution and is a useful tool for studying atom dynamics. In this paper, we apply the electromagnetically induced transparency (EIT) technique to 2DES in a three-level atom, and find out that the number of peaks (troughs) will become more due to the introduction of EIT. Also, the height of the peaks (the depth of troughs) will change from constant to a damped oscillation. These findings may help us obtain more information about the dynamics of excited states.
