Abstract. Characteristics of non-linear scattering of powerful pulses of Q-switched YAG:Nd3+ laser in an aqueous suspension of submicron-sized black-body particles has been investigated. Proposed is a model describing the results of experiments. This model involves laser-induced overheating of suspended particles and vaporization of surrounding water with subsequent rapid growth of vapor shells around the particles.
Keywords: laser-induced scattering, non-linear processes, black-body suspensions.
