2020-10-19 Tomasz Krehlik: Electromagnetically induced transparency in ladder-type system of Rubidium atoms

EIT phenomenon can be employed as a spectroscopy method with resolution below the natural linewidth of the probed transition. The experimental setup which allows to perform EIT measurments with wide range of excited states (including Rydberg states with n ≈≈ 50) will be presented, as well as preliminary results and theoretical model explaining the signal’s shape.
