Stimulated Raman scattering of linearly polarized light from degenerate and selectively populated atomic sublevels of potassium have been observed. The scattered radiation has a polarization perpendicular to that of the incident beam. Such transition can take place between substates of different or of the same atomic level. In the latter case, the frequencies of the incident and scattered beams are equal and the polarizations are perpendicular. The induced transitions are associated with parametric four-wave coupling possessing also characteristic polarization properties.Stimulated Raman scattering of linearly polarized light from degenerate and selectively populated atomic sublevels of potassium have been observed.

Pump-probe experiments on the rare-earth paramagnet ${\text{Dy}}_{3}{\text{Al}}_{5}{\text{O}}_{12}$ demonstrate that coupling between light and magnetism on the subpicosecond time scale cannot be adequately described by the thermodynamic model of the inverse Faraday effect but instead must be described microscopically by stimulated magneto-Raman scattering. Light-induced paramagnetic resonance, predicted by the thermodynamic theory, is not observed in ${\text{Dy}}_{3}{\text{Al}}_{5}{\text{O}}_{12}$ , however, the formation of a coherent superposition between other magnetic sublevels of the ${\text{Dy}}^{3+}$ -ion's ground-state multiplet is measured. It is shown that coherence can only be induced between magnetic levels which are connected by the Raman selection rules.Pump-probe experiments on the rare-earth paramagnet ${\text{Dy}}_{3}{\text{Al}}_{5}{\text{O}}_{12}$ demonstrate that coupling between light and magnetism on the subpicosecond time scale cannot be adequately described by the thermodynamic model of the inverse Faraday effect but instead must be described microscopically by stimulated magneto-Raman scattering.
