An oscilloscope based method for pulsed Optically Detected Magnetic Resonance in an ensemble of NV centers in diamond

In this work, we have demonstrated the acquisition of pulsed ODMR data with the help of a high speed oscilloscope. We show how the on-system data averaging and the memory of the oscilloscope can be utilized to obtain high SNR data at high speeds. The problem of experimental drift and the strategy for eliminating the same is discussed. Two distinct methods of data acquisition and processing are discussed, and their applicability to different pulsed protocols is investigated. Rabi Oscillations, Ramsey Interferometry, T1 measurement, and spin echo are demonstrated.
