Using laser light it is possible to polarize the electron spin of a colour center in diamond even at room temperature. Resonant microwave radiation can then be used to transfer this polarization to surrounding nuclear spins. Repeating this procedure many times over can lead to very strongly (hyper)-polarized nano-diamonds that may be useful as a contrast agent in MRI. One of the challenges is the random orientation of nanodiamonds in a solution which makes it difficult to achieve resonance with microwaves. In this work we explore the use of microwave frequency combs, i.e. the use of many microwave frequencies to achieve better performance.
