Induced Transparency

We present experimental results on the influence of magnetic fields and laser polarization on electromagnetically induced transparency (EIT) using Rydberg levels of ^{87}87Rb atoms. The measurements are performed in a room temperature vapor cell with two counter-propagating laser beams at 480 m and 780 m in a ladder-type energy level scheme. We measure the EIT spectrum of a range of ns_{1/2}ns1/2 Rydberg states for n=19-27n=19−27, where the hyperfine structure can still be resolved. Our measurements span the range of magnetic fields from the low field linear Zeeman regime to the high field Paschen-Back regimes. The observed spectra are very sensitive to small changes in magnetic fields and the polarization of the laser beams. We model our observations using optical Bloch equations that take into account the full multi-level structure of the atomic states involved and the decoupling of the electronic JJ and nuclear II angular momenta in the Breit-Rabi regime. The numerical model yields excellent agreement with the observations. In addition to EIT related experiments, our results are relevant for experiments involving coherent excitation to Rydberg levels in the presence of magnetic fields.

Dark Resonance

The prospects of using Fg = 1-Fe = 3 magnetically induced (MI) transitions of the 87Rb D2 line to form optical resonances in strong magnetic fields up to 3 kG have been experimentally demonstrated. A micrometer-thick cell filled with the Rb atomic vapor is used. A simple and convenient method for determining the magnetic induction with a micron spatial resolution is presented. In this case, there is no need for a reference frequency spectrum. The probability of the MI transition in the magnetic field range of 0.3–2 kG may exceed the probability of a “normal” atomic transition; therefore, it is reasonable to use MI transition at the frequency of “coupling” or probe lasers in Lambda- and V systems to form EIT- resonance (also called dark resonance) in the process of electromagnetically induced transparency (EIT). The formation of dark resonances in strong magnetic fields, when there is a frequency shift of the dark resonance up to ~ 10 GHz, has a number of practical applications. Note that when using “ordinary” atomic transitions in the Lambda- system for magnetic fields of > 1 kG, dark resonances are practically absent.
