An experimental study and a numerical simulation of the propagation of laser radiation with wavelengths of 1064 nm and 532 nm in disordered media have been carried out. The samples were suspensions of rutile in DMSO with different volume fraction of scatterers. The effect of the volume fraction of scatterers in the suspension on the photon lifetime in the medium has been investigated. To determine the influence of the volume fraction of scatterers on the Raman efficiency Raman spectroscopy was carried out. It has been shown that at large volume fraction of scatterers decreases the volume of light-matter interaction. The maximum increase in the Raman signal achieved in suspensions is fourfold.
