Deterministic laser-writing of nitrogen-vacancy centres in high purity diamond
Year: 2025
Type: article
Abstract: We report the deterministic writing of single nitrogen-vacancy defects in commercially available high purity diamond using only laser processing. The positioning accuracy of the single defects is around 250 nm and about 20% of the written defects display near transform-limited optical transitions at a temperature of 5 K. The results represent a significant step towards defect-engineered devices using colour centres as coherent spin-photon interfaces for quantum technologies, and shed light on the physical mechanism for laser-induced vacancy diffusion in diamond.
