Simulations of light scattering processes with incident laser beams
(Gaussian beams) by an extension of a program of
C. Hafner which is based on
the multiple multipole method (MMP). MMP belongs to the
generalized multipole techniques (GMTs) and has more flexibility than Mie
theory, related to particle shape. You can download an example
of a sphere moving through a laser beam:
