“…Since the first laser demonstration on Nd:YAG ceramics in 1995 [1], more and more research is focused on transparent ceramic laser materials [2,3]. In addition to Nd 3+ doped ceramic laser materials, Yb 3+ doped ceramics attracted much attention by virtue of their broad absorption and emission bandwidth and long fluorescence lifetime [4].…”

In this work, Yb:YAG transparent ceramics were prepared through aqueous gel-casting forming technique. Single-phase Yb:YAG nanopowders with mean particle size of 170 nm were used to prepare Yb:YAG slurries. The rheological properties of Yb:YAG slurries were investigated as a function of pH value and the dispersant content. It was found that the maximum zeta potential was achieved at pH = 11.5 with 2 wt% dispersant content (based on the weight of Yb:YAG powders). And then, the stable slurries with different solid loading (30-40 vol%) were prepared by ball milling and casted to form green bodies. The influence of the solid loading on microstructure of green bodies was investigated. The result showed that the green body with solid loading of 38 vol% had no deformation and exhibited homogeneous and compact microstructure with a relative density of 56.3 %.Finally, high optical quality Yb:YAG ceramic was obtained with the in-line transmittance of 81.2 % (1 mm thick). Graphical Abstract Highly transparent Yb:YAG transparent ceramics were prepared through aqueous gel-casting forming technique starting from the raw materials of single-phase Yb:YAG nanopowders.

“…Some optimized sintered laser ceramics even demonstrated equal or superior optical quality compared with conventional laser single crystal [5]. Furthermore, the use of nanopowders with homogenous composition within each particle allows for uniform distribution of dopants in the ensuing ceramic body.…”

We have successfully developed high-quality laser-grade yttrium aluminum garnet (YAG), and lutetium oxide (Lu 2 O 3 ), using a novel combustion chemical vapor condensation (CCVC) technique based on a proprietary NanoSpray Combustion process. The purity of the nanopowders was >99%. Nanopowders with different dopants have been synthesized over a 10-200 nm size range, with low-cost, high-purity precursors that are viable for large-scale production. Great strides have also been made in developing highly dense (>99% theoretical density) polycrystalline Nd-doped YAG pellets using vacuum sintering and hot isostatic pressing (HIP). This method is an alternative to the Czochralski method for making single-crystal ceramic bodies, which has several disadvantages including high cost, size, shape restrictions, and limitations in Nd concentrations (∼1 at %). Nanomaterials also enable higher percentages of Nd to be incorporated into the YAG lattice which improves laser efficiency and >85% near IR transmission, thereby reducing scattering losses associated with larger grain-size polycrystalline materials.
