Abstract:

New ceramic materials based on yttrium oxide Y2O3 with isovalent (Yb2O3, Nd-2 O-3, and Lu2O3) and heterovalent (ZrO2 and HfO2) 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 Y2O3 ceramics doped with zirconium and hafnium ions, the emission bandwidth and the lifetimes of the F-4(3/2) and F-2(5/2) levels of Nd3+ and Yb3+ ions, respectively, are presented. It is shown that the nonradiative population of the F-4(3/2) levels of neodymium ions is due to their dipole-dipole interaction with Zr3+ and Hf3+ ions. Laser generation in {[}(Yb0.01Lu0.24Y0.75)(2)O-3](0.88)(ZrO2)(0.12) ceramics with disordered crystalline structure was achieved at a wavelength of 1034 nm with a differential efficiency of 29\%.
