On the basis of Smoluchowski equation the theory of the
spatial-temporal
dynamics of the concentration response of the polarizable particles in a
liquid under the action of the gradient force in the field of a
nonresonance spatially modulated laser radiation has been
developed. It is shown that the action
of a nonresonance radiation with a spatially-modulated intensity on the ansemble
of particles causes their motion, which leads to the formation of
concentrational spatial structures corresponding to the intensity
modulation. The kinetic
of formation and subsequent relaxation of particle-concentration spatial structures induced by
the two interfering coherent Gaussian beams and a Bessel
beam of zeroth order has been investigated.
Key words: spatial-temporal dynamics, gradient force, laser
radiation, polarizable particles, diffusion
