Laser writing in diamond: devices to gems

Diamond’s strength comes from a tightly bound lattice of carbon. Nevertheless, laser writing with ultrashort laser pulses can be used for internal modification of the diamond lattice with 3D resolution and a myriad of applications. This talk will cover advances in laser written diamond devices, focusing on three recent developments: (i) fabrication of embedded nanocarbon networks for novel electrical structures; (ii) precision laser processing with spectral feedback for creation of single nitrogen vacancy and tin vacancy defects for quantum technology; (iii) rapid manufacture of subsurface serial numbers for diamond gem stone traceability initiatives.
