    Comparison of Nd:YAG optical ceramics produced by different sintering routes
    (Видавництво Львівської політехніки, 2012) Doroshenko, А. G.; Kosyanov, D. Yu.; Маteychenko, P. V.; Matveevskaya, N. A.; Parkhomenko, S. V.; Puzikov, V. M.; Tolmachev, A. V.; Yavetskiy, R. P.; Kopylov, Yu. L.; Kravchenko, V. B.
    Nd:YAG ceramics were fabricated by solid-state reactive sintering of commercial powders and vacuum sintering of custom made co-precipitated nanopowders. The densities, microstructure, average grain size, residual porosity, optical transmittances of the sintered ceramics were compared. Nd:YAG ceramics produced by solid-state reactive sintering possess higher transmittance compared to vacuum-sintered ceramics from coprecipitated nanopowders, which is however still lower than that of single crystals. The possible ways to improve optical quality of Nd:YAG ceramics are discussed.
