Synthetic single crystal diamond, method of producing synthetic single crystal diamond, and infrared optical component

Abstract

A synthetic single crystal diamond in which a content ratio of nitrogen based on the number of atoms is 1 ppm or less and a content ratio of boron based on the number of atoms is 0.01 ppm or more and 3 ppm or less, wherein the content ratio of the boron based on the number of atoms is more than the content ratio of the nitrogen based on the number of atoms, and no absorption peak exists in a wavenumber range of 2790 cm−1 or more and 2810 cm−1 or less in an infrared absorption spectrum of the synthetic single crystal diamond measured by Fourier transform infrared spectroscopy.
