Bessel beams, propagationally invariant beams, and axicons: An historical and tutorial review

Published 8 Sep 2025 in physics.optics | (2509.06354v1)

Abstract: The Bessel beam is discussed, including its historical development. We present the relationship with the Arago Spot, annular pupils, axicons and pupil filters. We also discuss Bessel-Gauss beams; higher order Bessel beams; electromagnetic polarization properties; waveguide and resonator modes; polychromatic and pulsed beams; one-dimensional Airy beams; extended depth of focus; and light sheets and photonic nanojets.
