The spectral and lasing parameters of Yb 3+ ions in zirconium dioxide crystals with a stabilised cubic structure (fianites) are studied. It is found that the absorption and luminescence spectra of Yb 3+ in these crystals are characterised by a considerable inhomogeneous broadening. The nature of this broadening is investigated and the model of optical centres consistent with the properties of the inhomogeneous spectra of Yb 3+ in the cubic zirconium dioxide crystal is proposed. It is shown that fianites can be used in solid-state lasers. Lasing in Yb 3+ ions in diode-pumped fianite crystals was obtained and studied.
