摘要

本文对铌酸锂晶体中掺杂和热处理产生的点缺陷进行了研究。分析了氧化和还原过程对纯样品和掺杂样品的影响。特别是考虑可见光和红外光学吸收、光伏行为、顺磁共振和全息固定参数的结果，以了解铁和不同浓度的抗光学损伤杂质共掺杂晶体的光折变特性和光学损伤抑制。本文还讨论了羟基中心的行为及其在光折变全息固定中的作用。

Point defects physics in lithium niobate related to optical damage resistance, photorefractive holographic properties and applications

In this work some aspects of point defects produced in lithium niobate crystals by doping and thermal treatments are studied. The effect of oxidation and reduction processes on pure and doped samples is analyzed. In particular, results of visible and infrared optical absorption, photovoltaic behavior, paramagnetic resonance and holographic fixing parameters are considered to understand the photorefractive properties and optical damage inhibition in crystals co-doped with Fe and different concentrations of optical damage resistant impurities. The behavior of OH-centers and its role on photorefractive hologram fixing is also considered.
