Stimulated Raman Scattering of Light in Glycerol under Picosecond Laser Excitation

We record stimulated Raman scattering spectra in chemically-pure glycerol with the formation of two Stokes satellites with equidistant Raman frequencies ν = 2889 cm − 1 . To excite the scattered radiation, we employ short pulses of the second optical harmonic of a YAG:Nd 3+ laser with a wavelength of 532 nm. Using the fundamental harmonic of the YAG:Nd 3+ laser λ = 1064 nm, we convert the infrared Stokes component of stimulated Raman scattering into the visible range of the spectrum with the help of a nonlinear crystal of barium titanate. The large Raman shift of the Stokes components of stimulated Raman scattering makes it possible to use glycerol to convert laser radiation into different spectral ranges.
