| Abstract: | The two-beam coupling process and the fanning noise in a Ce:KNSBN crystal are experimentally studied as a function of the pump beam modulation frequency and the duty ratio. The results show that the fanning noise is restrained and the quality of the reconstructed image is improved with a suitable modulation frequency. |
| Keywords: | Photorefractivity Fanning Volume holographic storage Reproduction improvement |
