The generalized Lorenz-Mie theory describes the electromagnetic scatte
ring of a Gaussian laser beam by a spherical particle. The most intens
ive computational aspect of the theory concerns the evaluation of the
beam-shape coefficients in the general case of an off-axis location of
the scatterer. These beam-shape coefficients can be computed starting
from the set of beam-shape coefficients for an on-axis location by us
ing the addition theorem for the spherical vector wave functions of th
e first kind under a translation of the coordinate origin. (C) 1997 Op
