Abstract

Two gratings are recorded in photorefractive crystal Ce: (K _0.5Na_0.5)_0.2(Sr_0.61Ba _0.39)_0.9 Nb₂O₆ (Ce: KNSBN) by angle-multiplexing and denoted as G₁ and G₂, respectively. It is found that the peak position of the diffraction efficiency η as a function of the angle between the two incident beams 2θ of G₁ is at 44°. But if single grating in this crystal is recorded only, the peak position is at 36°. The result is theoretically explained by using a perturbative expanding method to the hopping model.
