Electromagnetically Induced Transparency

Kowalski K., Cao Long V., Dinh Xuan K., Głódź M., Nguyen Huy B., Szonert J.

In the initial part of the paper, the principles of the electromagnetically induced transparency (EIT) in basic three-level schemes are sketched, and some applications of this phenomenon are described. Next a presentation follows of a five-level EIT model of Bloch equations, which was developed to reconstruct multipeak cascade-EIT spectra registered in a sample of cold 85Rb atoms in MOT. The respective experiment is also described. The achieved good agreement between theory and performed experiment is documented and discussed.

In this paper, using the general master equation in the dipole interaction and the rotating-wave approximation, we will explain the experimental results obtained by Warsaw Group for Electromagnetically Induced Transparency in four-level lambda scheme of cold rubidium atoms. The theoretical calculations are in good agreement with the experimental data.
