Modal decomposition of Bessel-Gaussian beams

Presented by Ms. Thandeka MHLANGA on 9 Jul 2013 from 17:40 to 18:40
Type: Poster Presentation
Session: Poster1
Track: Track C - Photonics

Abstract

Bessel beams have many properties which make them to be an interest of study. Their known properties include that they are non-diffractive of a certain region, they form an annular ring at far distances and they self reconstruct after encountering an obstruction. In this poster we will demonstrate an efficient way of measuring the Bessel beam parameters using a simple experimental setup where spatial light modulators will be used to generate Bessel-Gauss beams and to measure the orbital angular momentum (OAM) state they carry as well as their radial component using a modal decomposition technique.
