Abstract
An experimental study of electromagnetically induced two- photon transparency (EITT) in rubidium atomic vapor at room temperature is presented. A four level system is considered, involving the two-photon absorption process 5S1/2 to 8S1/2 via an intermediate state 5P3/2, and the single- photon control process 5P3/2 to 5D5/2. A controlling pump laser beam is employed to coherently couple the 5P3/2 and 5D5/2 states, thus producing two dressed intermediate states, which give rise to destructive interference in the two-photon transition. Fluorescence from 8S1/2 to 5P1/2 is used to monitor the 5S1/2(Fequals3) to 8S1/2(Fequals3) two-photon absorption. An induced two-photon transparency of about 80% has been obtained at resonance; the experimental results are in good agreement with the general theory of Agarwal, when the appropriate spectroscopic parameters are employed.
