Abstract
The lasing characteristics of 1 % Nd :YAG and 0.8 % Nd :YAG laser ceramics synthesised, respectively, at the Institute of Electrophysics, Ural Branch, Russian Academy of Sciences and at the Institute of Radio Engineering and Electronics, Fryazino Branch, Russian Academy of Sciences are studied. Lasing was obtained in all the samples with a slope efficiency from 7 % to 25 % and a maximum output power exceeding . Intrinsic absorption and scattering losses in the ceramics are estimated.
