Abstract

A CVD single crystal diamond material suitable for use in, or as, an optical device or element which has an optical absorption such that a sample of at least 0.5 mm thickness has an optical absorption coefficient at a wavelength of 1.06 žm of less than 0.09cm<-1> or at a wavelength of 10.6 žm of less than 0.04cm<-1>. Also a CVD single crystal diamond material which has an optical scatter such that for a sample of at least 0.4 mm thickness the forward scatter at 1.064 žm integrated over a solid angle from 3.5 to 87.5{ from the transmitted beam is less than 0.4%. 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.
