The theoretical analysis of the dynamic holograms efficiency in the nonideal nanoparticle gas is carried out. The electrostrictive mechanism of optical nonlinearity of the medium is due to the forces operating on the particles of the dispersed phase in gradient light field. The recording of the dynamic hologram is significantly non-linear process at high intensities of radiation. The amplitude of phase grating depends exponentially versus intensity but it saturates at the high filling factor due to the repulsion effect.
