Abstract :
We have measured damped oscillations of two beam coupling in a photorefractive BaTiO/sub 3/ crystal during the grating translation experiment and derived an analytic expression for damped oscillation of space charge field. It is found that the theory developed excellent agrees with the experimental result.
