Author:Litvin, IA; Khilo, NA; Forbes, A; Belyi, VNDate:Feb 2010The authors report on two resonator systems for producing Bessel–like beams with longitudinally dependent cone angles (LDBLBs). Such beams have extended propagation distances as compared to conventional Bessel– Gauss beams, with a far field ...Read more
Author:Forbes, A; Dudley, Angela L; Roux, SDate:Dec 2010Research at the Mathematical Optics Group uses "twisted" light to study new quatum-based information security systems. In order to understand the structure of "twisted" light, it is useful to start with an ordinary light beam with zero twist, ...Read more
