We consider some peculiarities of the evolution of processes of
stimulated scattering in liquid transparent particles in the presence
of ponderomotive action of a light field. We observed the
occurrence of sharp deformations in the Descartes ring zone, which
exceeds by more than 1 order of magnitude the deformations of the
remaining particle surface. Investigation of the dynamics of the
evolution of droplet deformations has made it possible to consider
these deformations as the main cause of suppression of stimulated
scattering indicated in the experiments. An analytical expression
was derived to evaluate the decrease of the Q factor of
droplet quasi-normal eigenmodes caused by perturbation of the particle
shape from the spherical. Our study revealed that the larger the
Q factor of the droplet eigenmodes, the greater the
influence of surface deformation.
