Ultrafast Control of Material Optical Properties via the Infrared Resonant Raman Effect
The Raman effect, inelastic scattering of light by lattice vibrations (phonons), produces an optical response closely tied to a material's crystal structure. Here we show that resonant optical excitation of IR and Raman phonons gives rise to a Raman-scattering effect that can induce giant shifts to the refractive index and …
