提出了一个简单的数学模型来描述对称可调谐双艾里波束（STDAB） [Opt. Lett. 39 (2014) 2370；光学学报，38 (2013)1286；光学学报，37 (2012)3402 [j]。该光束由两个具有可调参数的传统艾里光束组成，它们具有几个显著的特征。例如，光束的强度分布可以是高斯分布，椭圆高斯分布，矩形高斯分布或哑铃形，具有不同的可调参数。基于柯林斯积分公式，导出了STDAB通过近轴ABCD光学系统的解析表达式。对于特殊情况，研究了光束在自由空间和手性介质中、通过薄透镜和通过分数阶傅里叶变换系统时的传输特性。
A simple mathematical model is proposed to describe symmetric tunable dual Airy beam (STDAB) [Opt. Lett. 39 (2014) 2370; Opt. Lett. 38 (2013) 1286; Opt. Lett. 37 (2012) 3402]. This beam is composed of two conventional Airy beams with a tunable parameter which have several distinguishing features. For example, the intensity distribution of the beam can be Gaussian, elliptical Gaussian, rectangular Gaussian or dumbbell shaped with difference tunable parameters. Based on the Collins integral formula, an analytical expression of the STDAB passing through a paraxial ABCD optical system is derived. For special cases, the propagation properties of the beams in free space and in chiral medium, passing a thin lens and passing a fractional Fourier transformation system are studied.
