Fabrication and laser output of transparent Nd：YAG ceramics from microwave synthesized precursors

We report the laser output of transparent Nd：YAG （Nd：Y3Al5O12） ceramics fabricated from Nd：YAG precursors through the microwave-assisted homogenous precipitation （MAHP） method. Pure phase and uniform Nd：YAG nano-powders with average sizes less than 100 nm were obtained by heating treatment of.the Nd...

Description
Summary:We report the laser output of transparent Nd：YAG （Nd：Y3Al5O12） ceramics fabricated from Nd：YAG precursors through the microwave-assisted homogenous precipitation （MAHP） method. Pure phase and uniform Nd：YAG nano-powders with average sizes less than 100 nm were obtained by heating treatment of.the Nd：YAG precursor particles aged for 6 d in vessel with humidity of 30%-50% at 25℃. Transparent Nd：YAG ceramic pellets were obtained by vacuum sintering at 1730℃ for 10 h. Laser output （305 roW） with a slope efficiency of 5.1% was realized through an end-pumped configuration. Our results indicate that the MAHP method could potentially be used for the fabrication of laser ceramic products,
