Spectral Hole Burning and Fluorescence Line Narrowing of Si Center in CVD Diamond

Abstract

In this presentation we report on several spectral features associated with Si impurity in diamond related to spectral hole-burning. Diamond, with its hardness and high temperature stability, is a potentially useful material for high temperature hole-burning storage. The first hole-burning in bulk diamonds [1] was observed from color centers in the spectra of N3 at 415 nm, H4 at 496 nm, N-V at 637 nm, and GR1 at 741 nm. Recently, hole-burning was observed for color centers N-V at 637 nm and 574 nm of electron irradiated chemical-vapor deposited (CVD) diamonds [2].
