Abstract

Neodymium-doped LNA laser crystals (LaxNd1-xMgAl11O19) have been pumped by laser diode arrays emitting around 800 nm. With longitudinal pumping using two 200 mW diode arrays focussed on the crystal end, 10 mW of power was obtained at 1.054 μm. With the insertion of a Lyot filter and a thin etalon, tuning across the 1.082 μm band was possible. Tuning the LNA laser output to the resonance transition of helium-4 (23S1-23P1) at 1.083 μm enabled us to optically pump the metastable helium atoms in a discharge cell and record magnetic resonance signals. Transverse pumping of the LNA crystals by a high-power, quasi-cw array was also successfully demonstrated. © 1987.
