| Abstract: | The temperature dependence of photorefractive parameters of Cu:KNSBN crystal has been investigted.It is demonstrated that the gain coefficient Γ of two-wave coupling is a function of the crossing angle 2θ of two beams at different temperature.According tofitting of Γ-2θ experimental date in Reference 6,the temperature dependence of the effective photorefractive charge density,the effective electro optical coefficient and the hole-electron competition factor have been derived.These results are useful to optical information processing. |
