All-optical hyperpolarization of electron and nuclear spins in diamond

Low thermal polarization of nuclear spins is a primary sensitivity limitation for nuclear magnetic resonance. Here we demonstrate optically pumped (microwave-free) nuclear spin polarization of \(^{13}\mathrm{C}\) and \(^{15}\mathrm{N}\) in \(^{15}\mathrm{N}\)-doped diamond. \(^{15}\mathrm{N}\) polar...

Summary:Low thermal polarization of nuclear spins is a primary sensitivity limitation for nuclear magnetic resonance. Here we demonstrate optically pumped (microwave-free) nuclear spin polarization of \(^{13}\mathrm{C}\) and \(^{15}\mathrm{N}\) in \(^{15}\mathrm{N}\)-doped diamond. \(^{15}\mathrm{N}\) polarization enhancements up to \(-2000\) above thermal equilibrium are observed in the paramagnetic system \(\mathrm{N_s}^{0}\). Nuclear spin polarization is shown to diffuse to bulk \(^{13}\mathrm{C}\) with NMR enhancements of \(-200\) at room temperature and \(-500\) at \(\mathrm{240~K}\), enabling a route to microwave-free high-sensitivity NMR study of biological samples in ambient conditions.
