摘要: 艾里光束作为一种具有自加速特性的无衍射光束, 在光镊、光学成丝、成像、表面等离子激发等众多 领域都具有应用潜力。而在艾里光束基础上引入涡旋项可以丰富光场特性, 同时利用艾里光束特性与涡旋相位 特性为光场分布调谐提供了更大的灵活性, 也引入了更多的动力学演化特性。以直角坐标和极坐标系下艾里光 束的特性与应用为切入口, 系统介绍了各类艾里涡旋的参数调谐与演化特性, 包括直角坐标和极坐标系下单个艾里涡旋在各个情况下的演化特性、产生方式与应用, 以及直角坐标和极坐标系下的艾里涡旋叠加光束的奇特 性质等, 为系统了解艾里涡旋参数及动力学特性提供参考, 进而为产生具有更加丰富性质的光场打下基础, 对扩大艾里涡旋的实际应用领域具有指导意义。

Abstract: As a non-diffractive beam with self-accelerating characteristics, Airy beam has application potentials in many fields such as optical tweezers, optical filamentation, imaging and surface plasma excitation. The introduction of vortex on Airy beam can enrich the characteristics of light field. Taking advantage of the characteristics of both Airy beam and vortex phase, greater flexibility for the tuning of light field distribution could be achieved, as well as more interesting dynamic evolution features. Starting with the characteristics and applications of Airy beams, the parameter tuning and evolution characteristics of a single Airy vortex are systematically introduced, including its evolution characteristics, generation ways, derived light field and applications, and also the peculiar properties of the superposition beams of Airy vortex in rectangular and polar coordinates respectively, which provides a reference for the systematic understanding of Airy vortex parameters and dynamic characteristics, lays a foundation for the generation of light field with richer properties, and has guiding significance for expanding the practical application field of Airy vortex.

Key words: wave optics, Airy beam, Airy vortex, mode superposition, dynamic evolution, orbital angular momentum, structured light
