Abstract. Evolution of anatase phase for the TiO 2 nanocrystals at their laser irradiation is researched by the method of combinational light dispersion. The observed changes of intensity, frequency and halfwidth of TiO 2 phonon lines are interpreted taking into account the effects of nonstoichiometry, superficial strains and phonon confinement. The found out parameter changes in the low frequency E g mode show that laser irradiation results in substantial improvement of the structural ordering in the area of TiO 6 octahedrons bonds.

Keywords: Titanium dioxide, Intercalation, Anatase, Raman spectroscopy.
