We present for the first time, to the best of our knowledge, a 1359 nm continuous-wave (CW) Nd:Lu2O3 laser based on the 4F5/2 4F13/2 transition. The use of a pump module with 16 passes through the crystal allowed the realization of a Nd:Lu2O3 thin-disk laser with 3.52 W of CW output power. The slope efficiency with respect to the incident pump power was 21.4%, and the fluctuation of the output power was better than 3.55% in the given 2 hour. The beam quality factor M2 is 1.14 and 1.18 for tangential direction and sagittal direction, respectively. ((c) 2012 by Astro Ltd., Published exclusively by WILEY-VCH Verlag GmbH & Co.
