Abstract
Stimulated Raman scattering (SRS) from an individual liquid droplet (∼30-μm radius) has been observed for H2O, D2O, and ethanol. The occurrence of a series of spectrally narrow peaks that are regularly spaced in wavelength is consistent with morphology-dependent resonances of the droplet, which acts as an optical resonator. The input intensity required to achieve the SRS threshold for the droplet is considerably less than that for the liquid in an optical cell.
