Observation stimulated Raman scattering in nanocrystallineSc₂O₃ ceramics

Abstract

Efficient room-temperature steady-state high-order stimulated Raman scattering under picosecond pumping was excited in highly transparent nanocrystalline ceramics based on cubic Sc 2 O 3 . All recorded Stokes and anti-Stokes lasing components in the visible and near-IR were identified and attributed to the χ (3) -active vibration mode ω SRS ≈ 419 cm -1 of this novel nonlinear-laser material.
