N2 - We investigate electromagnetically induced transparency (EIT) for one-photon and resonant two-photon transitions in rubidium atomic vapors. One-photon transparency is obtained in the 5S-5P-5D three level ladder system. At the same time, we study electromagnetically induced transparency in the two-photon transition (EITT) from the 5S to the 7S state resonant with the 5P intermediate state, when the latter is coupled to the 5D state by a control beam. The dependence of the transparency profile on the controlling laser intensity, linewidth, and detuning is investigated. Experimental results are obtained for isotopes 85Rb and 87Rb characterized by different hyperfine structures. Our findings for both the one-photon and the resonant two-photon transparency agree well with the prediction from three and four-level theory, respectively, with independently determined spectroscopic parameters.
