Using a highly efficient Raman set‐up, which allows a Raman spectrum to be recorded in less than 1 s, morphology‐dependent resonances in optically levitated microdroplets of water–glycerol mixtures were studied. In addition to the output resonances, where the Raman frequency coincides with an electromagnetic sphere resonance, input resonances could also be demonstrated. The latter are observed when the evaporating droplet reaches a radius which, together with the wavelength of the incident laser lgith, fulfils the resonance condition for the cavity modes of a sphere. Preliminary results for droplet size change during evaporation of a particular droplet in the micrometre range are presented.
