Optical probing of cold trapped atoms



W. Fox, Sarah L. Gilbert, Leo W. Hollberg, J. H. Marquardt, Hugh Robinson


Transitions between excited states of laser-cooled and laser-trapped rubidium and cesium atoms are probed by use of fiber and diode lasers. High-resolution Doppler-free spectra are detected by observation of the absorption and fluorescence of light from the intermediate level of two-step cascade systems. The optical double-resonance spectra show Autler-Townes splitting in the weak probe limit and more complicated spectra for a strongly coupled three-level system.
