Conference Name Rydberg-EIT Spectra in Room-Temperature Atomic Vapors
Content We will discuss the Rydberg-EIT spectra measured with room-temperature or hot Rb-87 atoms. Two phenomena in the spectra were observed and not completely understood. (1) While the EIT peak corresponding to the coupling transition from |5P_3/2, F’=3> to the Rydberg state of 57S or 55D was clearly seen, that from |5P_3/2, F’=2> to the same Rydberg state was missing. (2) The EIT peak height as a function of the probe intensity was measured at several Rydberg states, probe-coupling polarization configurations, and coupling intensities. The data showed a universal behavior that the EIT peak height initially increases, reaches a maximum, and eventually decreases with the probe intensity. The discussion is organized as the followings. I will first give a brief introduction and then chair the discussion. Two students will present what we know and what we do not know about the two phenomena in details. Questions, suggestions and comments are very welcome during the presentations.
