Description
Summary:A non-synchronously-numerating experimental system is applied in this research. The effect of the incident beam intensity I and the beam incident angle 8 on beam fanning effect is investigated with a singular beam incident on Ce：KNSBN crystal. The results show that the beam fanning effect strongly depends on land 8. The threshold effect of/for the beam fanning in Ce-KNSBN crystal is observed, and the threshold intensity of incident beam keeps the same value of 38.2 mW/cm^2 for different 8, and the steady beam fanning intensity ltsat reaches a peak at θ=-15° under the same I. In addition, the effect of the incident beam modulated on the beam fanning noise and holographic storage in Ce：KNSBN crystal is studied. And the results suggest that the beam fanning noise is effectively suppressed, and the quality of the reappearance image is greatly improved.
