双Pearcey光束的角动量特性研究

Angular momentum characteristics of dual Pearcey beams

作为一种新型的形式不变光束,双Pearcey光束是近来产生的一种新Pearcey光束。从光束结构看,双Pearcey光束仿佛是两个互为对称的经典Pearcey光束面对面的简单叠加。在光束光学形态的基础上,为揭示双Pearcey光束的光学本性,研究了双Pearcey光束角动量特性。研究结果为深入揭示形式不变双Pearcey光束的光学拓扑结构奠定了基础。

As a kind of form-invariant new beams,dual Pearcey beams are a kind of new member of the family of Pearcey beams. Seeing from the beams structure,dual Pearcey beams can simply be regarded as the face-to-face superposition of two symmetrical classical Pearcey beams. In order to really reveal the optical nature of dual Pearcey beams,we studies the angular momentum features of dual Pearcey beams. The research results lay the road for revealing the optical topological structure of form-invariant dual Pearcey beams.
