畴工程铁电晶体是一类在非线性光学领域应用广泛的微结构功能材料。本文综述了近十年来利用畴工程晶体进行非线性光束整形的研究进展。介绍了非线性惠更斯-菲涅耳原理、非线性体全息和焦散设计等在线性光学中具有类似意义的新发展的设计方法。利用所提出的方法，实现了非线性光束整形、多重函数积分、Airy光束生成和任意曲线轨迹。作为一个额外的自由度，光束的轨道角动量是通过域工程产生和控制的。提出了该领域的讨论和未来发展方向。
Domain engineered ferroelectric crystals are a type of microstructure functional material that is used widely in the area of nonlinear optics. Herein, research processes in the area of nonlinear beam shaping using domain engineered crystals in the past decade are reviewed. The newly developed design methods, such as the nonlinear Huygens-Fresnel principle, nonlinear volume holography, and caustic design, which have analogs in linear optics, are introduced. Using the proposed methods for nonlinear beam shaping, multiple function integration, generation of Airy beams, and arbitrary curved trajectories are realized. As an extra degree of freedom, orbital angular momentum of light beams is generated and manipulated through domain engineering. Discussions and future directions in this field are presented.
