Bessel–Gauss beams [1] form an interesting
class of physically realizable approximations of
the propagation-invariant Bessel fields [2–4]. Due
to the Gaussian apodization of the ideal Bessel
amplitude distribution, the beam retains its diffraction-
free properties only within a finite range but
its propagation can be described everywhere by
rather simple analytical formulae. 求高手帮忙
