Abstract

Diamond is a wide-bandgap semiconductor known for its distinguished properties. It also hosts many defects, such as the Nitrogen-Vacancy (NV) center. Since one can generate such defects through fs-laser micromachining, an investigation was made to determine the optimal experimental conditions for such feat, where a Yb:KGW fs-laser system operating at 1030 nm, producing 216 up to 1000 fs pulses at 197.5 KHz was used. Microstructures were produced by varying pulse duration and excitation fluence. Through confocal microscopy image analysis, it was determined that NV center generation is proportional to the excitation fluence and inversely proportional to the pulse duration.
