摘要
用一种新的测量方法在不同入射光强下同时观测了Fe:LiNbO3和(Fe,Tb):LiNbO3晶体中光致折射率变化Δns、吸收系数α和光电导σph与入射光强I的依赖关系, 并从理论上对观测结果给予了初步解释。
Abstract
A new method is used to measure the photorefractive index change Δn s (at saturation), the nonlinear absorption coefficient α and the photoconductivity σ ph at different input light intensity I simultaneously. The preliminary explanation for the experimental results is given.
