Holographic scattering noise in LiNbO3:Fe:Ru crystals

Holographic scattering noise in LiNbO3:Fe:Ru crystals is investigated in this paper. The effect of doped concentration and the incident light intensity on the holographic scattering noise is investigated. The experimental results show that the transmitted light intensity is fluctuated in the initial stage of scattering noise evolution, and the sample with highly doped concentration has the lowest scattering noise level among three LiNbO3:Fe:Ru samples. The results are analyzed on the basis of multi-wave coupling amplification mechanism and the saturated space charge field.
