Abstract

We investigate Xe129-Cs (D1,D2) spin exchange optical pumping (SEOP) at high Xe densities (∼0.12-2.44 amagat) using newly available high-power (≥40 W) laser diode arrays and compare with Xe129-Rb D1 SEOP under similar conditions. At elevated Xe densities, the spin-exchange rate (per alkali-metal atom, γ) for Cs-Xe129 is ∼1.5-fold greater than that for Rb-Xe129. Higher spin-exchange rates and lower Xe129 spin-destruction rates for Cs-Xe129 versus Rb-Xe129 contribute to ∼twofold improvement in Xe129 nuclear spin polarization measured at 9.4 T-with the largest gains observed at the highest Xe densities.
