Abstract

A new type of controllable auto-focusing beam array named annular Tricomi-Gaussian beam array (ATGBA) is introduced. The auto-focusing ability of ATGBA can be manipulated by the number of beamlets N, the complex constants α and β of beam parameters. The focusing position or the focal length of ATGBA can be controlled by the transverse displacement parameter d and the beamlet order l of Tricomi-Gaussian beam (TGB). Interestingly, enhancing auto-focusing ability and extending focal length for an ATGBA can be simultaneously realized by selecting lower beam order l of TGB. The auto-focusing ability of ATGBA is about 4 times of auto-focusing Bessel-Gaussian beam (ABGB) under the same condition. In addition, the Poynting vector and the OAM density of ATGBA are provided.

可控自聚焦环形三高斯波束阵列的传播动力学

介绍了一种新型可控自动聚焦波束阵列——环形三高斯波束阵列（ATGBA）。ATGBA的自动聚焦能力可由光束数N、光束参数的复常数α和β来控制。ATGBA的聚焦位置或焦距可以通过三高斯光束（TGB）的横向位移参数d和光束阶数l来控制。有趣的是，通过选择低光束阶的TGB，可以同时增强ATGBA的自动对焦能力和延长焦距。在相同条件下，ATGBA的自动对焦能力约为贝塞尔-高斯光束（ABGB）的4倍。此外，还给出了ATGBA的Poynting矢量和OAM密度。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
