| Popis: | We report on the first observation of the nonlinear cascading χ(3) ↔ χ(3) effects in UV spectral range and second harmonic generation stipulated by the ``defect'' nonlinearity under one-micron pumping in crystalline ceramics based on cubic oxides Sc2O3 and Lu2O3. Broadband their multi-wavelength Stokes and anti-Stokes combs with the extension of 10475 cm-1 (for Sc2O3) and 8232 cm-1 (for Lu2O3) were recorded as well. |
