将体全息的概念应用于光学超晶格的非线性谐波产生的设计中。产生的谐波可以看作是由入射基波产生的全息像。与传统的准相位匹配方法相比，这种新方法在处理特殊光束的非线性产生等复杂的非线性过程时具有明显的优势。作为一个例子，我们实验实现了二次谐波艾里光束，结果与数值模拟结果很好地吻合。
The concept of volume holography is applied to the design of an optical superlattice for the nonlinear harmonic generation. The generated harmonic wave can be considered as a holographic image caused by the incident fundamental wave. Compared with the conventional quasi-phase-matching method, this new method has significant advantages when applied to complicated nonlinear processes such as the nonlinear generation of special beams. As an example, we experimentally realized a second-harmonic Airy beam, and the results are found to agree well with numerical simulations.
