title: Effect of the phase velocity and spatial overlap of spherical resonances on sum-frequency generation in droplets.
abstract: The spectrum of the third-order sum-frequency generation (TSFG) that results from the electric fields of the laser E(omega(L)) and of the first-order Stokes stimulated Raman scattering E(omega(1s)) is dependent on the droplet radius. In addition to the amplitude and spatial overlap of the three generating E(omega)'s and of the generating and resultant waves, phase matching between the generating and TSFG waves is an important parameter. We discuss the range of phase velocities of the generating and TSFG waves, which must be tuned to coincide with spherical resonances in order to be guided waves circumnavigating the droplet rim.
