Electrically Induced Transparency in 6Li Atoms

The effect of electrically induced transparency occurs when a three-level system with one forbidden transition is exposed to strongly coherent radiation. Under certain conditions, the absorption in the medium drastically reduced. As a result, sharp jump in the dispersion of light in the medium near the resonance point appears. This leads to a decrease in the group velocity of light. The effect of electrically induced transparency can find applications in cooling chains of atoms, frequency conversion, and creation of optical quantum memory. In this work, we conducted an experiment to observe the effect of electrically induced transparency using lithium atomic vapor cell. In our experiment, we observed the effect of electro-induced light transparency on lithium atoms and investigated the behavior of the effect depending on temperature and relative beam intensities. We obtained the width of the EIT resonance for the D1 line of approximately 1.2 MHz.
