Abstract
High-quality holmium-doped Y3Al5O12 (YAG) ceramic is fabricated in sequence by tape-casting and vacuum sintering. The average grain size of the Ho:YAG ceramic is around 20 ?m with a fully dense microstructure. The inline transmittance of the sample is ?82% in visible and IR region. The fluorescence lifetime at 2088 nm is 8.17 ms. The excellent properties of the Ho:YAG ceramic demonstrate the tape-casting is a novel candidate process for the fabrication of Ho:YAG-based thin-chip or composite ceramics.
