摘要： A CVD single crystal diamond material suitable for use in, or as, an optical device or element. It is suitable for use in a wide range of optical applications such as, for example, optical windows, laser windows, optical reflectors, optical refractors and gratings, and etalons. The CVD diamond material is produced by a CVD method in the presence of a controlled low level of nitrogen to control the development of crystal defects and thus achieve a diamond material having key characteristics for optical applications.

摘要： A method of incorporating a mark of origin, such as a brand mark, or fingerprint in a CVD single crystal diamond material, includes the steps of providing a diamond substrate, providing a source gas, dissociating the source gas thereby allowing homoepitaxial diamond growth, and introducing in a controlled manner a dopant into the source gas in order to produce the mark of origin or fingerprint in the synthetic diamond material. The dopant is selected such that the mark of origin or fingerprint is not readily detectable or does not affect the perceived quality of the diamond material under normal viewing conditions, but which mark of origin or fingerprint is detectable or rendered detectable under specialised conditions, such as when exposed to light or radiation of a specified wavelength, for example. Detection of the mark of origin or fingerprint may be visual detection or detection using specific optical instrumentation, for example.
摘要翻译：在CVD单晶金刚石材料中加入诸如品牌标记或指纹的原产地标记的方法包括以下步骤：提供金刚石基底，提供源气体，解离源气体，从而允许同质外延金刚石生长;以及以受控的方式将掺杂剂引入源气体中，以便在合成金刚石材料中产生原点或指纹标记。选择掺杂剂使得原始标记或指纹不容易被检测到，或者在正常观察条件下不影响金刚石材料的感知质量，但是在特定条件下可检测或可检测起始或指纹的标记如当暴露于例如特定波长的光或辐射时。原点或指纹的检测可以是例如使用特定光学仪器的视觉检测或检测。
