Abstract:

Single crystalline neodymium-doped yttrium-aluminum-garnet (Nd:YAG) is the state of the art in solid state lasers. However, YAG single crystals have several disadvantages including high manufacturing cost, limited size and shape, and low Nd concentrations (~ 1 at%). Sintering nanocrystals into transparent polycrystalline solids would alleviate many of the manufacturing limitations associated with growing YAG single crystals using the Czochralski method. nGimat, in collaboration with Penn State University and VLOC, proposes to further optimize and scale nGimat's high volume, cost-effective NanoSpray process for production of these nanopowders and their subsequent processing into polycrystalline lasing material. In Phase I, nGimat succeeded in producing high purity, crystalline nanopowders that were pressed and sintered into polycrystalline YAG and 1 at% Nd-doped YAG pellets. In addition, nGimat demonstrated the ability to modify average nanocrystal diameter, crystallinity, composition, and Nd-doping concentration. The objectives of this Phase II program are to produce 10 kg batches of ultrapure, 10 to 100 nm diameter, unagglomerated yttrium aluminum oxide nanopowder using nGimat's NanoSpray process. Successful completion of Phase II objectives will position nGimat to sell nanopowder to military agencies, military subcontractors, and commercial partners.
