Abstract

Ultrashort laser pulses can modify in a precisely controlled way the structure of diamond crystals and of the natural and artificial impurities that they may contain. On one side, the carbon crystalline structure of diamond can be turned into graphite by intense laser pulses to write conductive channels inside the material, which may then be used to develop high spatial and temporal resolution 3D detectors for high-energy particles. On the other, controlled irradiation by sequences of short laser pulses can selectively activate single quantum emitters based on natural or artificially-implanted ion impurities, which may find applications in many sectors of emerging quantum technologies.
