✦ Synopsis
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 Sc~2~O~3~ and Lu~2~O~3~. Broadband their multi-wavelength Stokes and anti-Stokes combs with the extension of 10475 cm^-1^ (for Sc~2~O~3~) and 8232 cm^-1^ (for Lu~2~O~3~) were recorded as well.
