Abstract
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 13C and 15N in 15N-doped diamond. 15N polarization enhancements up to -2000 above thermal equilibrium are observed in the paramagnetic system Ns0. Nuclear spin polarization is shown to diffuse to bulk 13C with NMR enhancements of -200 at room temperature and -500 at 240 K, enabling a route to microwave-free high-sensitivity NMR study of biological samples in ambient conditions.
