We demonstrate in this letter an ability to manipulate threshold concentrations for the observation of cavity enhanced Raman scattering (CERS) in microdroplets, and to enhance the intensity of scatter from a selected component in binary component (nitrate/water) droplets. Measurements from droplets of varying composition have shown that the concentration of the minor component can be quantitatively determined from the optically seeded signal. Various strategies are described by which this method may be more generally applied to enhance stimulated Raman scattering intensities of minor components in multicomponent droplets.
