Webexhibited by Helmholtz equation, that presents the optical beam characteristics, is the designated Gaussian profile beam. In every transverse surface, its intensity distribution presents a Gaussian function with circular symmetry centered on the beam axis, i.e., on its propagation axis [28]. This beam type is one of the most important and simplest Web4 apr. 2013 · In this work we construct Gaussian beam approximations to solutions of the high frequency Helmholtz equation with a localized source. Under the assumption of nontrapping rays we show error estimates between the exact outgoing solution and Gaussian beams in terms of the wave number k, both for single beams and … WebThe 0, 0 order of this family represents a new mathematical model for the fundamental mode of a propagating Gaussian beam.
