The primary interest in the finite-energy Airy beam derives from the special properties possessed by the maximum intensity at its central lobe. However, the defining spatial dependence, the Airy function, is an oscillatory function that consists of decaying side lobes. For some applications these side lobes may create deleterious effects. Fortunately, a nonsymmetric apodization of the beam in Fourier space is shown to enhance the central lobe as the side lobes are reduced and clipped. The properties of the central lobe are unaffected over a large proportion of the propagation path.
有限能量艾里光束的主要关注点源于其中心叶瓣的最大强度所具有的特殊性质。然而，定义其空间分布的艾里函数是一个由衰减旁瓣组成的振荡函数。对于某些应用，这些旁瓣可能会产生有害影响。幸运的是，在傅里叶空间中对光束进行非对称的变迹处理，可以在减小和裁剪旁瓣的同时增强中心叶瓣。在传播路径的很大一部分范围内，中心叶瓣的特性不受影响。
