Beschreibungen/Notizen

• The optical properties and microstructure of transparent ceramics synthesised by different reactive sintering routes are studied. It is found that the residual porosity of optical ceramics is directly related to the homogeneity of the microstructure of initial compacts, which can be estimated by the existence of particle agglomerates larger than in initial nanopowders. A qualitative correlation is established between the residual porosity, the optical losses and the lasing slope efficiency of ceramics. The maximum laser efficiency was observed in the samples with the lowest porosity .
