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 13 C and 15 N in 15 N -doped diamond. 15 N polarization enhancements up to -2000 above thermal equilibrium are observed in the paramagnetic system N s 0. Nuclear spin polarization is shown to diffuse to bulk 13 C 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.
