Airy pattern formed by A Circular Laser Beam
Description
In optics, a Gaussian beam is a beam of electromagnetic radiation whose transverse electric field and intensity (irradiance) distributions are well approximated by Gaussian functions. Many lasers emit beams that approximate a Gaussian profile. A circular laser beam with uniform intensity profile, focused by a lens, will form an Airy pattern at the focal plane of the lens.
