摘要

文章专门讨论了铌酸锂晶体的非线性效应。文章展示了利用不同时刻不同持续时间的激光辐射获得的数字全息干涉图重建动态相位变化的可能性。利用氦氖激光器和氦镉激光器在掺有不同浓度铁离子的铌酸锂晶体上记录了全息图，并计算了衍射效率。此外，还研究了伽马射线对铌酸锂晶体和铌酸锂:铁晶体光学特性的影响。与此同时，还确定了样品的带隙减小，折射率、吸收系数和光折射灵敏度因此增加了数倍。

Investigations of Nonlinear Optical Properties of Lithium Niobate Crystals

The article is devoted to nonlinear effects in lithium niobate crystals. The possibility of using digital holographic interferograms obtained with the help of laser radiation of different duration at different moments of time for the reconstruction of dynamic phase changes is shown. Holograms were recorded on lithium niobate crystals doped with iron ions in various concentrations using He-Ne and He-Cd lasers, and the diffraction efficiency was calculated. Also, the effect of gamma radiation on the optical properties of LiNbO3 and LiNbO3:Fe crystals was studied. At the same time, it was determined that the band gap of the samples decreases, as a result of which the refractive index, absorption coefficient and photorefractive sensitivity increase several times.
