title: Cavity-mode identification of fluorescence and lasing in dye-doped microdroplets.
abstract: Recent advances in an aerosol-generation technique have permitted the accurate identification of optical resonance-mode features of micrometer-sized freely falling droplets for several different optical processes. Both input and output resonant features of fluorescence and lasing from dye-doped microdroplets were assigned to specific spherical cavity modes by using two independent procedures: (1) by matching observed fixed-angle elastic laser light scattering as a function of droplet size to calculated scattering intensities from the Lorenz-Mie theory, and (2) by matching observed resonance peaks to computed cavity-mode positions by automated correlation. Agreement between these two complementary techniques establishes high confidence in the resulting mode identifications. Assignments of observed emission peaks provide insight into droplet-emission mechanisms.
