Beam propagation factor of apertured super-Gaussian beams
Abstract:Starting from the generalized truncated second-order moments definition, an explicit expression for the beam propagation factor (M 2-factor) of apertured super-Gaussian beams is derived and illustrated with numerical examples. Some special cases of our analytical result are discussed.
