Propriedades de feixes Hermite-Bessel não-difratantes generalizados

Abstract

This work is divided in two parts. In the first part, we will study some properties of a nondiffractive class of beams known as Hermite-Bessel beams. We will show both, theoretically and experimentally, their self-imaging and self-healing properties after it passes through an obstacle placed on the path of propagation. The angular spectrum analysis is employed to understand the effects involved. In the second part of this work, we generalize the Poincaré sphere for Bessel beams of order higher than 2. Then, we introduce high order Hermite-Bessel beams which show up naturally in the decomposition and take place at the Equator on the Poincaré sphere.
