Abstract
We have observed whispering gallery modes in the inelastic emission from a 9.8 microm polystyrene bead coated with a monolayer of AlexaFluor 488 dye. Using a separate near-IR trapping laser and an Ar+ excitation laser enables us to isolate and study a single dye-coated bead in a colloidal suspension without causing any bead damage.
