Optical Double Resonance with Laser-Induced Fluorescence Detection [and Discussion]

The saturation of level populations induced in a molecule by an intense laser beam may be probed by a second beam at the same or a different frequency. A number of schemes have been based on this principle for simplifying complex spectra or for achieving sub-Doppler resolution. Fluorescence detectio...

Summary:The saturation of level populations induced in a molecule by an intense laser beam may be probed by a second beam at the same or a different frequency. A number of schemes have been based on this principle for simplifying complex spectra or for achieving sub-Doppler resolution. Fluorescence detection provides the sensitivity for studies on free radicals and other transient molecular species. The two beams may be provided by two separate lasers, or by sideband modulation of a single laser. These techniques are reviewed. Emphasis is placed on recent studies of hyperfine structure, of Stark splittings, and of Zeeman splittings.
