摘要：

The possibility of using microwave heating for sintering of optical oxide ceramics and the advantages of this method are considered. Sintering of Yb-0.1:(YLa)(1.9)O-3 ceramics by heating with 24-GHz radiation is studied. The compacts for sintering are prepared from nanosized powders obtained by high-temperature synthesis from acetate-nitrates of rare-earth metals. The effect of addition of lanthanum oxide and of the uniaxial pressing conditions on the microstructure and optical transmission of ceramics is studied. Lasing at a wavelength of 1030 nm with an efficiency of 7.5% is achieved in ceramic samples of the (Yb0.05Y0.1La0.85)(2)O-3 composition under pumping by a laser diode at a wavelength of 940 nm.
