Synthesis and characterization of high concentration Nd3+ doped YAG nanopowders for laser applications

Abstract

Herein, neodymium-doped yttrium aluminum garnet (Nd:YAG) ceramic powders were fabricated via a wet chemical reaction method followed by heating in air. The structural studied confirmed the formation of single phase Nd:YAG nanocrystallites without any intermediate phase at 1000 °C, and the average particle size was calculated to be 260 nm. According to the reflectance results, the highest absoption of the synthesized powders was observed at 808 nm. Therefore, A laser diode (808 nm) with power output about 1000 mW was used as a pump source and the emission spectra was recorded. Upon IR excitation, the present sample showed intense emission at around 1064 nm and found to be potential for solid state lasewr devices.
