An attempt is made to check by experiment the assumption that the 2nd order Stokes radiation in collinear direction is generated from the primary light by the same mechanism as the 1st order radiation. If is found that the 1st order Stokes beam does not have a sufficiently high intensity over a sufficiently long interaction lenght to explain the generation of the observed 2nd order Stokes radiation as exclusively attributable to this mechanism. An alternative theory is advanced according to which the molecular vibrations generated in the 1st order Stokes process contribute to this effect in the small-signal range. This allows a more plausible explanation of the experimental results. The experiments were performed with benzene at λ = 0.53 μm because this substance exhibits strong stimulated Raman scattering without selffocusing at this wavelenght.

Stimulated Raman

Processes of Raman scattering of quasi-single-photon pulses in a single-mode optical fiber with pumping are theoretically considered. The peculiarity of the scattering is that the pumping creates non-equilibrium molecular vibrations, which significantly increases the probability of Raman scattering in the optical fiber. Non-equilibrium vibrations are expected to be when the stimulated Raman scattering takes place for the pump pulse. As a result, the length of the optical fiber has been estimated where the probability of the Raman scattering is increased
