  The interaction of laser pulses with the Cauliflower mosaic virus (CaMV) in a
Tris-HCl pH7.5 buffer is investigated. 20 ns ruby laser pulses are used for
excitation. Spectra of the light passing through the sample and reflected from
it are registered with the help of a Fabri-Perot interferometer. Stimulated
low-frequency Raman scattering (SLFRS) in a CaMV suspension is registered. The
SLFRS frequency shift, conversion efficiency and threshold are measured for the
first time, to the best of our knowledge.
