Abstract
The combined effect of electrostriction and radiative absorption in the formation of laser induced gratings in fluids is calculated. For pure electrostrictive gratings, the reflectivity is a damped oscillation with alternately higher and lower maxima. The damping is determined by viscosity and heat transfer. The normalized difference in height is determined by the thermal conductivity of the medium. Therefore, in principle, a separate determination of viscosity and thermal conductivity is possible. Measurements have been performed in the nonresonant or pure electrostrictive domain for argon and nitrogen.
