Microwave spectroscopy for diagnostics of nitrogen vacancy defects in diamond samples

Abstract

A setup is described that combines microwave spectroscopy with optical excitation and detection of luminescence of NV- colour centers in diamond crystals. The parameters of the system (design of the microwave antenna, microwave power and timing, and fast optical detection) allow studies of relaxation properties of the NV- defects and manipulation of their spin properties. © 2013 Photonics Society of Poland.
