Abstract
The paper is devoted to a theoretical investigation of laser-stimulated homogenization of regularly volume-structured and porous media with near-critical average density (close to the density corresponding to plasma resonance for the wavelength of the incident laser radiation). A concept of two-stage homogenization is proposed and theoretically substantiated: the first stage of fast partial smoothing of the mass distribution due to collisions of plasma flows in laser-heated and evaporated solid elements of the material structure and the second stage of slow complete smoothing of the density distribution due to viscosity dissipation of hydrodynamic perturbations. The properties of laser radiation absorption in a porous material are discussed and the high efficiency of internal “ volume” absorption of a laser pulse in porous media of average density significantly (by an order of magnitude) higher than the critical density is predicted.
