| Abstract: | High-order Raman parametric generation was excited in the visible and near-IR regions on the Stokes and anti-Stokes lines of Y3Al5O12 single crystals and nanocrystalline ceramics. All generation components, as well as the χ(3)-active vibrational modes of these materials, were identified. In connection with the extensive use of the Nd3+-and Yb3+-doped Y3Al5O12 crystals and, in recent years, nanocrystalline Y3Al5O12: Nd3+ ceramics in laser physics and quantum electronics, the applied aspect of the observed nonlinear properties of these materials is outlined. |
