Holoor艾里光束发生器

艾里光束是一种非衍射波形，不会随光束传播而散开，并且在行进时呈现出弯曲的外观。

艾里光束也具有自由加速的特性。随着传播，它弯曲以形成抛物线弧。
理想的艾里光束的横截面将显示出主强度区域，并且一系列相邻的，发光度较低的区域逐渐缩小到无穷大。
HOLO/OR建议使用特殊的DOE元素将高斯光束转换为艾里光束。

Characteristics of Airy beam.

(a) Measurement of beam acceleration of the Airy beam OPO as a function of propagation distance. Solid line (black) represents theoretically predicted acceleration, (red) is the quadratic fit to the experimental data (dots). (Inset) Variation in the width (FWHM) of the central lobe of the Airy beam over propagation. Solid line (red) is linear fit to data (dots). (b–e) Verification of self-healing property of the output beam of the Airy beam OPO. (f) The line profile of the beam at a distance z?=?10?cm (blue), z?=?60?cm (red), z?=?120?cm (brown) from the Fourier plane.
