Multi-wavelength nonlinear parametric χ^(3)^-effects were observed in highly transparent Y~2~O~3~ and Y~3~Al~5~O~12~ nanocrystalline ceramics under picosecond pumping at 300 K. All recorded Stokes and anti-Stokes components in the visible and near IR were identified and attributed to the stimulated

✦ Synopsis
Efficient room-temperature steady-state high-order stimulated Raman scattering under picosecond laser pumping in ceramics based on cubic Lu~2~O~3~oxide was discovered. All registered Stokes and anti-Stokes generation components were identified and attributed to the χ^(3)^-promoting vibration mode ω~SRS~≈ 392 cm^-1^of this novel crystalline laser-host material.
