Designing of spectroscopic characteristics in all-ceramic composite with layer-by-layer of Nd:Y/sub 3/ScAl/sub 4/O/sub 12/ and Nd:Y/sub 3/Al/sub 5/O/sub 12/

In this work, we fabricated the all-ceramic composite with layer-by-layer of Nd:Y/sub 3/ScAl/sub 4/O/sub 12/ (YSAG) and Nd:Y/sub 3/Al/sub 5/O/sub 12/ (YAG). We found that the tuning of the pumping wavelength made the spectral profile of fluorescence from the composite ceramics more even than that from single-layered Nd:Y/sub 3/Sc/sub x/Al/sub 5-x/O/sub 12/ ceramics. The technique of composite ceramics is proved to be useful because it can provide not only the compositional tuning but also a new controllability by the selection of the pump source.
