Inorganic materials exhibiting second-harmonic generation (SHG) are used to generate coherent radiation at wavelengths where solid-state laser sources are not available; that is, the deep UV (DUV) below 200 nm. Here, we describe the structure and optical property requirements that should be assessed to conclusively demonstrate the discovery of a functional DUV material for nonlinear optical (NLO) applications.
具有二次谐波产生 (SHG) 效应的无机材料可用于产生在固态激光源不可用的波长处的相干辐射；也就是说，在 200nm 以下的深紫外 (DUV) 区域。在这里，我们描述了应评估的结构和光学性质要求，以最终证明发现了一种用于非线性光学 (NLO) 应用的功能 DUV 材料。
