作者从无机材料、有机材料、高分子材料、无机／有机复合材料、金属有机材料５个方面对非 线性光学材料进行了分类综述，介绍了非线性光学材料的发展历程；讨论了它们的非光学性质、特点。(The author from the 5 aspects of inorganic materials, organic materials, polymer materials, inorganic / organic composite materials, metal organic materials were

光与超常介质相互作用时,光的磁场也变得很重要 。超常介质的色散磁导率导致光与超常介质的非线性相 互作用呈现出许多新特性。总结了超常介质中二阶非线性光学现象的国内外研究进展。(As the light interacts with the metamaterial, the magnetic field of light becomes important. The dispersive magnetic permeability of metamaterials leads to the non
