Abstract

Axisymmetric light beams are defined as light beams for which the component of the Poynting vector in the direction of propagation does not depend on the azimuthal angle in suitably chosen coordinate systems to reveal the symmetric property of the beam. It is shown that such beams are encoded in a set of beam-shape coefficients g n that are, however, defined in a more general way than usual in the case of Gaussian beams. Partial-wave expansions and properties of such beams are studied.
