Abstract

It is considered a construction possibility of high order paraxial singular beams from nonparaxial modes in a paraxial approximation. Laguerre-Gaussian beams cannot form from nonparaxial Legendre-Bessel beams by means of a relatively simple way over the whole optical axis on conventional approximate boundary conditions. Nevertheless, this operation may be realized at the expense of a new passage to the limit: a set of nonparaxial singular beams is unambiguously transformed into a set of guided modes of an optical fiber near its input. It is presented two practical significant cases.
