Nonlinear photonic crystals (NPCs) are transparent materials with a space‐dependent (often periodic) second‐order nonlinearity, which have been used extensively for the generation and control of coherent light at new frequencies. Thanks to recently introduced fabrication techniques capable of 3D nonlinearity engineering, explorations of nonlinear wave interaction with improved or unique functionalities of 3D configurations become possible. Here, the experimental example of nonlinear volume holography based on 3D NPCs is presented. The 3D modulation of nonlinearity enables reconstruction of optical beams at new frequency with predesigned phase and amplitude structures. Furthermore, a simultaneous synchronization of phase velocities of the fundamental reading beam and the generated new frequency beam ensures increased conversion efficiency. A proof‐of‐concept nonlinear holographic reconstruction of second harmonic vortex beam is obtained with an optically induced 3D nonlinear volume hologram in ferroelectric calcium barium niobate crystal. The results show the nonlinear volume holography based on 3D NPC provides a novel promising approach for efficient realization of optical complex beams at new frequencies, paving the way for applications in all‐optical signal processing, super‐resolution imaging, and 3D laser displays.

3D非线性光子晶体中的非线性体积全息
非线性光子晶体（NPC）是具有空间依赖性（通常是周期性的）二次非线性的透明材料，已广泛用于在新频率下产生和控制相干光。由于最近引入的能够进行3D非线性工程的制造技术，探索具有改进或独特3D配置功能的非线性波相互作用成为可能。在此，给出了基于3D NPC的非线性体积全息术的实验示例。非线性的3D调制可通过预先设计的相位和幅度结构重建新频率的光束。此外，基本读取光束和所产生的新频率光束的相位速度的同时同步确保提高的转换效率。用铁电铌酸钙钡晶体中的光诱导3D非线性体积全息图，获得了二次谐波涡旋光束的概念验证非线性全息重建。结果表明，基于3D NPC的非线性体积全息技术为在新频率下有效实现光学复杂光束提供了一种新颖的有前途的方法，为全光信号处理，超分辨率成像和3D激光显示器的应用铺平了道路。
