Transformations of spherical beam shape coefficients in generalized Lorenz-Mie theories through rotations of coordinate systems II. Axisymmetric beams

摘要

The description of laser beams in spherical coordinates requires the introduction of expansion coefficients named beam shape coefficients, or more specifically spherical beam shape coefficients. In part I of the present series of papers, we presented a general formulation for the transformation of spherical beam shape coefficients through rotations of coordinate systems, taking the form of a theorem of transformation. The present Part II deals with the special case of axisymmetric beams, more particularly of on-axis axisymmetric beams (such as Gaussian beams in an on-axis configuration).
