Over the past 36 years much research has been carried out on Bessel beams(BBs) owing to their peculiar properties, viz non-diffraction behavior,self-healing nature, possession of well-defined orbital angular momentum withhelical wave-front, and realization of smallest central lobe. Here, we providea detailed tutorial review on BBs from their inception to recent developments.We outline the fundamental concepts involved in the origin of the BB. Thetheoretical foundation of these beams was described and then their experimentalrealization through different techniques was explored. We provide an elaboratediscussion on the different kinds of structured modes produced by the BB. Theadvantages and challenges that come with the generation and applications of theBB are discussed with examples. This tutorial review provides referencematerial for readers who wish to work with non-diffracting modes and promotesthe application of such modes in interdisciplinary research areas.
