Scanning cavity-enhanced droplet spectroscopy: Tuning of the excitation laser for obtaining a continuous Raman spectrum

► A novel method, scanning cavity-enhanced droplet spectroscopy (S-CEDS) is developed. ► S-CEDS is an envelope of peak apexes of several cavity enhanced droplet spectra. ► S-CEDS provides continuous Raman spectra of liquid media with a high sensitivity. ► Obtained spectrum of S-CEDS coincides with a stimulated Raman spectrum.
