Abstract

We have experimentally and theoretically studied the causes of the transparency spectra of the 5S1/2-5P3/2-4D5/2 and 5S1/2-5P3/2-5D5/2 transitions of Rb87 atoms. Although, the two-photon resonance of the 5S1/2-5P3/2-4D5/2 transition was not Doppler-free in an Rb vapor, we observed the transparency phenomenon in this transition. The main cause of the transparency of the 5S1/2-5P3/2-4D5/2 transition was double-resonance optical pumping (DROP) due to two-step excitation, and that of the 5S1/2-5P3/2-5D5/2 transition was DROP and electromagnetically induced transparency due to two-photon coherence. We confirmed the experimental results with theoretical results calculated using the density matrix equations considering all the degenerate magnetic sublevels of both transitions of the Rb87 atoms.
