Abstract

Spatial characteristics of the four-wave radiation converter in an absorbing two-component medium consisting of a liquid and nanoparticles dissolved in it are studied in the approximation of large reflection coefficients. Shown that the presence of a negative sign of the electrostriction coefficient leads to the emergence of a dip in the spatial spectrum of the object wave, the position of which is determined by the parameters of the two-component medium. With increasing intensity of the pump waves the band half-width of cut out frequencies and the dip width are observed to increase, and also the band half-width of the most efficiently converted frequencies decreases.
