abstract = "This study examines the efficiency of spin hyper-polarisation of xenon nuclei via spin-exchange optical pumping in an optically opaque medium of rubidium vapour with almost complete absorption of resonant radiation. A numerical model is presented that takes into account the depletion of broadband pumping in opaque medium. The study shows that the proposed method of estimating average rubidium polarisation from absorption measurements of the optical pump radiation is applicable. The authors also demonstrate theoretically and experimentally the creation of a xenon polarisation gradient in an optically opaque medium and propose a technique to maximise signal from gradient-polarised xenon in NMR spectroscopy.",
