Abstract
In this work, we aim to characterize the Rabi oscillations of nitrogen-vacancy (NV) centers in diamond by implementing and utilizing a tailored experimental setup, where optical pulses are produced by an acousto-optic modulator (AOM). A central focus of this thesis was to design and construct a custom AOM around a TeO2 crystal. This was a necessity, because the commercial AOM failed during one of the experiments. The work that has been done involved extensive characterization of precise and synchronized timing. High-quality Rabi oscillations could not be measured due to time limitations and the breaking down of the commercial AOM. However, the thesis shows full control over pulse-sequencing, optical microwaves and NV excitation. This work provides a foundation for further spin dynamic experiments of NV centers. During the thesis software for controlled timing has been built, and the designing and integration of custom made electronics has been done, which can provide practical guidance for controlling quantum instrumentation devices. We highlight the engineering challenges in building quantum instrumentation from the ground up.
