The inversion of the wave front in stimulated Raman scattering (SRS) of ruby-laser radiation was registered in experiment, A pump beam of diffraction property was distorted by a factor 300 with an inhomogeneous phase plate, after which is excited the first Stokes component of SRS in carbon disulfide. The backscattered radiation after the return passage through the phase plate also had a diffraction-type divergence.
