Airy beam : ウィキペディア英語版
Airy beam
An Airy beam is a non-diffracting waveform which gives the appearance of curving as it travels.
==Physical description==
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. In reality, the beam is truncated so as to have a finite composition.
As the beam propagates, it does not diffract, i.e., does not spread out. The Airy beam also has the characteristic of freely accelerating. As it propagates, it bends so as to form a parabolic arc.
