Abstract
Energy transfer between two beams interfering in an electrooptic Bi 12SiO 20 crystal is analyzed as a function of the spatial frequency of the recorded hologram. We report high coefficients in a wide range of low spatial frequencies (Λ -1 ⋍44 mm -1) , when the drift length of the photocarriers becomes comparable to the fringe spacing. Exponential gain coefficients of Γ = 7 cm -1 have been reached for high intensity beams ratio (β > 10 4) and an optimized fringe displacement speed (moving grating recording). Application to coherent image amplification (×20) is shown.
