Abstract
Efficient laser operation of Nd:Lu<sub>2</sub>O<sub>3</sub> ceramic fabricated by Spark Plasma Sintering (SPS) was demonstrated. Transparent Nd:Lu<sub>2</sub>O<sub>3</sub> ceramic was successfully fabricated by Spark Plasma Sintering and its laser experiment was done. On the <sup>4</sup>F<sub>3/2</sub> to <sup>4</sup>I<sub>11/2</sub> transition, the obtained maximum output is 1.25W at the absorbed pump power of 4.15W with a slope efficiency of 38% and two spectral lines at 1076.7nm and 1080.8nm oscillated simultaneously. The slope efficiency of 38% is near two times higher than the previously demonstrated SPSed Nd:Lu<sub>2</sub>O<sub>3</sub> ceramic lasers. On the <sup>4</sup>F<sub>3/2</sub> to <sup>4</sup>I<sub>13/2</sub> transition, the laser operated at the wavelength of 1359.7nm and the maximum output of 200mW was obtained at the absorbed pump power of 2.7W.Entities:
