Computation of Nonlinear Optical Scattering by Droplets.

Abstract

Researchers have developed techniques required for a more thorough analysis of nonlinear optics in droplets and have developed models for some nonlinear processes. They have continued to develop techniques for modeling the resonances of perturbed spheres, based primarily on perturbation methods. Falling droplets deviate from perfect sphericity, and laser beams can induce inhomogeneities in the droplets. The techniques developed for perturbed spheres now allow us to model dispersive and absorptive optical bistability in droplets. They have modeled linear time-dependent internal fields in droplets illuminated with laser pulses, as a prelude to analyzing the nonlinear optical effects usually observed with pulsed laser illumination. They have developed techniques for computing the internal and scattered fields of droplets illuminated with Gaussian beams. Since droplets are often illuminated with Gaussian beams which may be focused on or outside the droplets, this capability is needed for a thorough modeling of nonlinear optics in droplets.
