Abstract
We show that a pulse can travel arbitrarily long distances without significant temporal spreading in a material with normal group velocity dispersion by endowing the pulse with a transversal Bessel-Gauss amplitude profile of suitable characteristics. Contrary to previous works. dispersion suppression is achieved with a finite-energy, transversally limited source, whose radius determines the largest dispersion-free propagation distance.
