Abstract
It is well-known that small (micrometers -sized) particles can be accelerated by a powerful laser pulse to considerable velocities. The laser-induced particle motion destroys the temporal coherence of the scattered light. The effect of particle motion on the coherence of scattered radiation is enhanced in concentrated suspensions of particles where the light scattering is substantially multiple. Hence the temporal correlation function of multiple-scattered light appears to be sensitive to the laser-induced particle flows. This point is of fundamental importance because traditional optical methods of particle flow diagnostics fail in the multiple-scattering regime. We analyze the possibility of optical diagnostics of laser-induced particle flows in concentrated multiple-scattering suspensions. We show that scattered radiation of the accelerating laser beam could give information on the `light-to-particles' momentum transfer, and, consequently, on the characteristic velocities of the laser-accelerated particles.
