The possibility of using microwave heating for sintering of optical oxide ceramics and the advantages of this method are considered. Sintering of Yb{sub 0.1}:(YLa){sub 1.9}O{sub 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 (Yb{sub 0.05}Y{sub 0.1}La{sub 0.85}){sub 2}O{sub 3} composition under pumping by a laser diode at a wavelength of 940 nm.
