Abstract: In the present paper we shall show that the modulational instability of an intense Laser beams of piezoelectric material BaTiO3 with SDDC using quantum hydrodynamic model. We analysis is carried out through the nonlinear dispersion relation of modulational and the threshold value of pump electric field (E0). An expression for the growth rate of acoustic wave through with the quantum and without quantum effect and also the compered the growth rate between them

Keyword: QHD model, modulational instability, SDDC (strain dependent dielectric constant), nonlinear dispersion relation, acoustic wave.
