Itis designed to measure absorption and polarization rotation induced by any of the two laser beams and also the visible fluorescence that resultsfrom decay of the excited states. Two home-built diode lasers are used to produce the optical fields that later interact with room temperaturerubidium atoms. Using counterpropagating beams allows velocity selection of the groups of atoms that interact with both laser beams. The systemwas tested in the 5 S → 5 P3/2→ 5 Djladder energy level configuration of atomic rubidium. Blue fluorescence (420 nm) that results from decayof the intermediate 6Pjstates is filtered and then measured with a photomultiplier tube. Absorption and fluorescence spectra provide mutuallycomplementary information about the interaction between the rubidium atoms and the two optical fields.All Rights Reserved © 2015 Universidad Nacional Autónoma de México, Centro de Ciencias Aplicadas y Desarrollo Tecnológico.
