摘要: 基于微分几何理论和衍射光学理论,给出了决定Pearcey光束光学结构的因素。通过数值模拟和实验,理论构造并实际产生了一簇光学拓扑结构不同的Pearcey光束。随后,它们的基本光学性质被研究。研究结果表明, Pearcey光束的结构灵活可控,因而有望在科学实验中发挥新的作用。Abstract: Based on differential geometry and optical diffraction theory, the determinants of optical structure of Pearcey beams are examined. We theoretically propose and experimentally observe a bundle of Pearcey beams with different optical topology structures. Besides, we have studied their properties and the results show that the structure of Pearcey beams can be flexibly controlled, hence they will be expected to play a new role in some research fields.
