摘要

非衍射波束，包括艾里波束、贝塞尔波束和马修波束，在先进光通信和动态波前工程方面显示出巨大的潜力。然而，在非线性光学系统中，它们的产生和场操纵仍然没有得到充分的探讨。本研究利用计算机生成全息技术，从理论上和实验上生成了不同阶数的非线性马修光束。采用二值编码和准多值编码两种不同的编码方法，分别获得了0、2、5、10阶马修波束的二次谐波图像。仿真和实验结果表明，与二进制编码方法相比，准多值编码方法具有更高的波束整形精度，并显著降低了衍射伪影。

Nonlinear generation of Mathieu beams by the quasi-multivalue-encoding method

Non-diffracting beams, including Airy, Bessel and Mathieu beams, demonstrate remarkable potential for advanced optical communications and dynamic wavefront engineering. However, their generation and field manipulation in nonlinear optical systems remain insufficiently explored. In this study, nonlinear Mathieu beams of various orders are generated theoretically and experimentally by computer generated holography. The second harmonic images are obtained for 0th-, 2nd-, 5th-, 10th- Mathieu beams via two different encoding methods: the binary encoding and quasi-multivalue-encoding method. Both simulations and experiments confirmed that the quasi-multivalue-encoding method achieves superior beam-shaping accuracy and significantly reduces diffraction artifacts compared to the binary encoding method.

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.
