Аннотация: New ceramic materials based on yttrium oxide Y<inf>2</inf>O<inf>3</inf> with isovalent (Yb<inf>2</inf>O<inf>3</inf>, Nd<inf>2</inf> O<inf>3</inf>, and Lu<inf>2</inf>O<inf>3</inf>) and heterovalent (ZrO<inf>2</inf> and HfO<inf>2</inf>) components are synthesized, and their spectroscopic properties are investigated. Possible channels of losses in the gain of stimulated radiation in the radiative transitions of Nd3+ and Yb3+ ions in ceramics with heterovalent additives are studied. The results of measurements of Y<inf>2</inf>O<inf>3</inf> ceramics doped with zirconium and hafnium ions, the emission bandwidth and the lifetimes of the 4F<inf>3/2</inf> and 2F<inf>5/2</inf> levels of Nd3+ and Yb3+ ions, respectively, are presented. It is shown that the nonradiative population of the 4F<inf>3/2</inf> levels of neodymium ions is due to their dipole-dipole interaction with Zr3+ and Hf3+ ions. Laser generation in [(Yb<inf>0.01</inf>Lu<inf>0.24</inf>Y<inf>0.75</inf>)<inf>2</inf>O<inf>3</inf>]<inf>0.88</inf>(ZrO<inf>2</inf>)<inf>0.12</inf> ceramics with disordered crystalline structure was achieved at a wavelength of 1034 nm with a differential efficiency of 29%. © 2015, Pleiades Publishing, Ltd.
