Preliminary experiments using Perot‐Fabry interferometers demonstrated the possibility of filtering selectively the fluorescence background from Rayleigh scattering excited by 25 ps pulses. Experiments aimed at extending the technique to spontaneous, Raman scattering are in progress. This technique is compatible with either single‐channel or multi‐channel detection of Raman spectra excited by mode‐locked ion, dye or solid‐state lasers.
