Measurement of Transition Dipole Moments in Molecular Lithium Using Electromagnetically Induced Transparency
Abstract
We have observed electromagnetically induced transparency(EIT) in two different three-level Doppler-broadened molecular systems using fluorescence detection. The optical fields were two continuous-wave, single-frequency dye and titanium sapphire lasers. In both Ë-type (co-propagating beams) and ladder-type (counterpropagating beams) systems the fluorescence reduction due to EIT is studied as a function of the intensity of the coupling field. Our theoretical predictions are in a very good agreement with the experimental results. We demonstrate here that the power dependent splitting of fluorescence excitation spectral lines can be used as a new spectroscopic tool for the measurement of transition dipole moment functions in molecular systems.
