GENERALIZED BESSEL-GAUSS BEAMS

In this paper we describe a superposition model for Bessel-Gauss beams , in which higher orders are included. An analogous model leads to a d ifferent class of beams, namely the modified Bessel-Gauss beams. Then a generalized set of beams, containing the previous beams as particula r cases, is introduced. The behaviour of these beams upon propagation is investigated, both analytically and numerically.
