Abstract
The optical and generation characteristics of 8.3(3) at. % Yb:YSAG ceramics (Y2,55Yb0,25Sc1,00Al4,2O12) made by solid solution powder sintering. Lasing was obtained on the basis of Yb:YSAG ceramics and the characteristics of laser radiation were studied at different transmittances of the output mirror of the resonator. The maximum generation power was 1.8 W at 3.6 W of absorbed pumping in the quasi-cw generation mode. The maximum differential efficiency was 57% for a mirror with a transmittance of 14.5%.
