Efficient laser operation based on transparent Nd:Lu2O3ceramic fabricated by Spark Plasma Sintering.
Efficient laser operation of Nd:Lu2O3ceramic fabricated by Spark Plasma Sintering (SPS) was demonstrated. Transparent Nd:Lu2O3ceramic was successfully fabricated by Spark Plasma Sintering and its laser experiment was done. On the4F3/2to4I11/2transition, 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:Lu2O3ceramic lasers. On the4F3/2to4I13/2transition, 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.
