The optical pumping of helium at 1083 nm is proving useful in applications involving magnetometry, polarized electron sources and neutron spin filters, but existing sources at 1083 nm are limited in efficiency, lifetime, reliability, compactness and power. The crystal laser material Nd:LuAlO3 (neodymium doped lutetium orthoaluminate) has ideal spectroscopic properties, but previous growths have displayed color centers that make lamp pumping impractical. Our previous experiments indicate that these color centers pose no short-term problems with low power near-infrared diode end-pumping.
