High spectral resolution infrared stimulated Rayleigh/Brillouin scattering in liquids

Summary form only given. Stimulated Rayleigh and stimulated Brillouin scattering provide information on the thermal and elastic properties of materials. These measurements may be performed at any wavelength for which the material is transparent. We demonstrate Rayleigh/Brillouin measurements at a wavelength of 1.064 /spl mu/m, where vibrational overtone or combination bands produce some absorption in organic liquids. This absorption causes stimulated thermal scattering, making the stimulated Rayleigh peak readily observable, and causing asymmetry in the stimulated Brillouin peak.
