Abstract

The Lithium niobate crystals doping is effective photo-induced crystals properties influence method. Therefor, this paper was devoted to experimental investigations of photorefractive and photochromic effects in lithium niobate crystals, doping with Fe: Mn, Fe: Cu, Fe9Ti and Fe: Hf impurity combinations. Separately doping with Fe, Cu, Ti, Hf crystals were used for comparison in experiments. The crystal absorbtion spectrums show, that the impurities interact in spite of small concentrations. Photorefractive sensibility determination was corried out with careful in this work.

双掺杂LiNbO3的光致变色和光折变效应机理

铌酸锂晶体掺杂是一种有效的光致晶体性能影响方法。因此，本文对掺杂Fe: Mn、Fe: Cu、Fe9Ti和Fe: Hf杂质组合的铌酸锂晶体的光折变和光致变色效应进行了实验研究。实验中分别掺杂Fe、Cu、Ti、Hf晶体进行比较。晶体吸收光谱显示，尽管浓度很小，杂质也会相互作用。在此工作中，进行了光折变敏感性的测定。
