Efficient laser operation of Nd:Lu 2 O 3 ceramic fabricated by Spark Plasma Sintering (SPS) was demonstrated. Transparent Nd:Lu 2 O 3 ceramic was successfully fabricated by Spark Plasma Sintering and its laser experiment was done. On the 4 F 3/2 to 4 I 11/2 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 2 O 3 ceramic lasers. On the 4 F 3/2 to 4 I 13/2 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.
