a light beam whose transverse intensity profile stays unchanged over long distances, such as a Bessel beam, in contrast to ordinary spreading by diffraction.

In optics, nondiffracting beam refers to a light beam whose transverse intensity profile stays unchanged over long distances, such as a Bessel beam, in contrast to ordinary spreading by diffraction. This meaning comes from Durnin (1987) in Physical Review Letters.[1]
