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℃.Tramparent Nd:YAG ceramic pellets were obtained by vacuum sintering at 1730℃ for 10 h.Laser output (305 mW) 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.
