摘要: 为了研究铌酸锂晶体中的光损伤,着重对掺铁铌酸锂晶体中光损伤的暗衰减效应进行研究,发现在薄样品中光损伤的暗衰减时间远大于在厚样品中的暗衰减时间,利用红外吸收光谱和喇曼光谱对这个现象的潜在机理进行了初步分析,综合几个实验结果发现,晶体厚度对光损伤的暗衰减是一个重要的影响因素.

Abstract: In order to research into the optical damage in iron-doped lithium niobate crystals,we investigated the decay behavior of the optical damage in iron-doped lithium niobate crystals.The dark decay time of the optical damage in thin crystal sheets was found to far exceed that in the thick crystal sheets.The OH-spectra and Raman spectra were performed in order to clarify the underlying mechanism.In conclusion,the thickness of samples greatly influences the optical damage.
