Multifrequency stimulated Raman scattering in ethanol under picosecond laser excitation

For the first time, stimulated Raman scattering (SRS) was detected in rectified ethanol upon excitation by ultrashort (55 ps) pulses of a YAG:Nd³⁺ laser operated at a wavelength of 355 nm. SRS of light is observed in the form of several Stokes components on the symmetric mode of the CH₃ group. The large Raman shift of the Stokes components, as well as the relatively high gain of stimulated Raman radiation, makes it possible to effectively use ethanol for the conversion of laser radiation into different spectral ranges.
