The formation of electrostrictive gratings in fluids is calculated by inclusion of viscosity and heat transfer. The reflectivity of the grating performs a damped oscillation with alternately higher and lower maxima. The normalized difference in height is determined by the thermal conductivity of the medium. Measurements have been performed for argon and nitrogen and are compared with the theory. Furthermore, the combined effect of electrostriction and radiative absorption is discussed.
