We demonstrate here experimental
129
Xe
polarisations of 80 %, approaching the theoretical limit
of 86% predicted by our previous models, and which has
been made possible by incorporation of a 50 W volume
holographic grating laser diode array to a mid-pressure
(2 bars) continuous-flow spin-exchange optical pumping
129
Xe
polariser.
