Collinear non-diffracting beams: classification and properties

Abstract

Non-diffracting laser modes and interfering non-diffracting beams have been extensively studied. Interfering nondiffracting beams generate novel laser modes. In this paper we accumulate various interfering conditions for nondiffracting beams and discuss the properties of the resultant beam. Contrasting intensity profiles and topological charge distribution are obtained on varying interfering conditions. Collinear propagation of non-diffracting laser beams is also reported. Show more
