Long range quasi-nondiffracting beams carrying orbital angular momentum

Author: Ismail, Y ; Barnes, G ; Mhlanga, T ; Belyi, V ; Forbes, A Date: Mar 2010 In this paper the authors outline an optical design for producing high-order Bessel-like beams with a z-dependent cone angle through the use of conventional optical elements, without the need for deliberate aberrations to be included.

Propagation of obstructed Bessel and Bessel–Gauss beams

Author: Litvin, IA ; McLaren, MG ; Forbes, A Date: Aug 2008 The investigation into Bessel beams has been a topic of immense research during the past 20 years, due to the interesting properties they display. Bessel beams not only exhibit diffraction free propagation, but also reconstruction of the ... Read more
