Optical readout of spin ensembles

Electron spin resonance provides means to very sensitive magnetic field sensors. At present charged nitrogen vacancies in diamond provide unique properties such as optical readout of the electron spin state and spin coherence above room temperature. This allows to use this system for magnetic field sensing applications. You will work on implementing an experimental platform for optical readout and microwave manipulation of electron spins in nitrogen vacancy centers in your thesis. For the setup you will use optical detection schemes and laser illumination. In addition, you employ microwave signals to manipulate the spin state in the nitrogen vacancy center. You will then use calibration measurements to quantify the performance of the new setup.
