We report the utilization of resonance-enhanced ionization to perform high-resolution spectroscopy on laser-cooled atoms. The technique is applied to the 5S 1/2 5P 3/2 5D J ( J = (3/2), (5/2)) optical double resonances of rubidium atoms in a magneto-optical trap. Ions generated when atoms in the double excited state absorb a single photon are detected, together with the induced fluorescence. The two detection channels are compared for this class of high-resolution spectroscopy experiment.
