An Airy beam is a non-diffracting waveform which doesn’t spread out as the beam propagates and gives the appearance of curving as it travels.
The Airy beam also has the characteristic of freely accelerating. As it propagates, it bends so as to form a parabolic arc.
A cross section of an ideal Airy beam would reveal an area of principal intensity, with a series of adjacent, less luminous areas trailing off to infinity.
HOLO/OR suggests special DOE elements which transform Gaussian beam to Airy beam.
