摘要：

An experimental setup for studies of morphology dependent resonances (MDRs) in Raman spectra of optically levitated microdroplets is described. This instrumentation is used for the study of MDRs in the Raman spectra of glycerol/water (3:1) droplets. Furthermore we show bow the MDRs observed in the Raman spectra and their change with time can be used to determine the radius and the index of refraction of single optically levitated droplets with very high accuracy. We further show how the results of this study can be used to calculate the efficiency factor of the radiation pressure and compare it with the experimental monitored laser power.
