Convergence criteria and optimization techniques for beam moments

نویسنده

چکیده

We consider the problem of the characterization of beams by moments of the field intensity in the aperture and its moments in the far field. The well known beam propagation factor, M2 P , is considered. We give convergence criteria for these factors and also discuss a new approach to optimization of the even moments of the far-field intensity.
