自弯曲艾里光束阵列产生的可调局域空心光束

利用艾里光束自弯曲特性，提出一种新的艾里光阵列产生的局域空心光束。这些艾里光束阵列以环形排列，当它们向前传播的同时又以向内的方向加速传播，从而形成环形局域空心光束。通过调节在初始输入平面上环形艾里光束阵列之间的间隔距离，可以很灵活实现调控局域空心光束大小。与传统的高斯激光叠加相比，多艾里光束的无衍射特性及相干叠加使得输出能量大大提高。数值模拟结果表明通过环形艾里光束的自加速特性可以形成局域空心光束。该灵活可控的局域光束可以为原子捕获与生命细胞操控提供更好的灵活性。

Abstract

We theoretically demonstrate a novel optical bottle beam that is produced by exploiting the self-bending characteristic of circularly arranged Airy beam (AB) arrays. The AB arrays propagate with an inward acceleration to generate such an optical bottle beam, whose size can be flexibly controlled by changing the spacing distance between ABs in the input plane. Moreover, the intensity of our proposed optical bottle beam is significantly increased in the output plane by superposing multiple coherent ABs, as compared to the case of the conventional Gaussian beam (GB). Numerical simulations are performed, the results of which show that the tunable optical bottle can be formed by exploiting the self-bending property of ABs. Some possible applications are also discussed. We believe that the intriguing characteristics of the tunable optical bottle can lead to novel techniques in medical treatment and atom manipulation.
