金刚石是能形成稳定的共价键晶格的质量最低的元素，这种晶格是高度对称和紧密结合的。其产生的极端特性，以及其合成的最新发展，导致了对各种光学技术（包括传感器，光源和光操纵器）材料的兴趣激增。其光学特性在许多方面与其他材料截然不同，因此提供了极大增强性能的诱人前景。电磁辐射与金刚石体和表面相互作用的详细知识库在辅助光学设计中具有重要意义。对于任何材料，表征光学性能的数据集都很大，金刚石也不例外，尽管它固有的晶格简单性。感兴趣的性质扩展到大范围的光学频率、强度和环境参数，以及金刚石形式的许多变体，包括缺陷和杂质水平、晶体尺寸和同位素组成。除了对这种古老物质的迷恋之外，它高度对称的结构和纯天然同位素含量（98.9% 12 C）为支撑固态理论提供了一个杰出的例子。因此，人们对金刚石进行了广泛的研究，其光学特性比大多数其他材料都更为人所知。以前已经报道了许多关于光学性质的优秀评论（例如参考文献[1 - 3]）。这些主要集中在线性光学性质上，经常关注外在现象，并且是从光学领域以外的角度写的，例如电子学和固态物理学。因此，有必要从光学设计的角度巩固数据。此外，金刚石的非线性光学性质至今尚未得到全面的研究。本章的目的就是要做到这一点，重点放在单晶金刚石（即纯IIa型金刚石1）的内在特性上。第一章

Diamond comprises the lowest mass element that can form a stable covalently bonded crystal lattice, and this lattice is highly symmetric and tightly bound. Its resulting extreme properties, along with the recent developments in its synthesis, have led to an explosion of interest in the material for a diverse range of optical technologies including sensors, sources, and light manipulators. The optical properties in many respects sit well apart from those of other materials, and therefore offer the tantalizing prospect of greatly enhanced capability. A detailed knowledge base of the interaction of electromagnetic radiation with the bulk and the surface of diamond is of fundamental importance in assisting optical design. For any material, the dataset characterizing optical performance is large and diamond is no exception despite its inherent lattice simplicity. The properties of interest extend over a large range of optical frequencies, intensities and environmental parameters, and for many variants of the diamond form including defect and impurity levels, crystal size, and isotopic composition. Over and above the fascination held for this ancient material, its highly symmetric structure and pure natural isotopic content (98.9% 12 C) provides an outstanding example for underpinning solid - state theory. As a result, diamond has been extensively studied and its optical properties are better known than most other materials. Many excellent reviews of optical properties have been reported previously (see e.g. Refs [1 – 3] ). These concentrate mainly on linear optical properties, often focus on extrinsic phenomena, and are written from perspectives outside of the fi eld of optics, such as electronics and solid - state physics. Consequently, there is a need to consolidate the data from the perspective of optical design. Furthermore, the nonlinear optical properties of diamond have not to date been comprehensively reviewed. The aim of this chapter is to do this, with emphasis placed on the intrinsic properties of single - crystal diamond (i.e., pure Type IIa diamond 1) ). The chapter 1
