Author:Ismail, Y; Barnes, G; Mhlanga, T; Belyi, V; Forbes, ADate:Mar 2010In 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.Read more

Author:Ismail, Y; Khilo, N; Belyi, V; Forbes, ADate:Sep 2012We present a method for generating higher-order Bessel beams with z-dependent cone angles. Such fields, if engineered correctly, are shape invariant during propagation and thus do not suffer from a transition from a Bessel-shaped intensity ...Read more
