中文摘要：

人工晶体学报生长了掺入不同浓度六价钼元素的铌酸锂晶体（LN：Mo），并研究了它们在351nm、488nm、532nm和671nm处的光折变性能。实验结果表明0．5mol％为最佳掺杂量，此时LN：Mo在各波段具有最快的响应速度和较好的饱和衍射效率。增加极化电流可以提高光折变性能，尤其当极化电流为145mA时，掺杂量为0．5mol％的LN：Mo晶体紫外光折变响应时间缩短至0．35s。这些优异的全息存储性能归因于Mo“占据了正常的Nb位。LN：Mo晶体是实现全色全息存储的潜力材料。

英文摘要：

Molybdenum doped lithium niobate crystals （LN： Mo） were grown under different polarization conditions and the photorefractive properties were investigated at 351 nm, 488 nm, 532 nm and 671 nm. The experimental results showed that 0.5mo1% is the best doping level as LN： Moo.5 always has the shortest response time and good saturation diffraction efficiency at each wavelength. Moreover, the photorefraction performances of LN： Mo0.5 crystals can be improved by enhancing the polarization current. Especially the response time of LN： Moo.5 could be shortened to as small as 0.35 s when polarized under the current of 145 mA. These features could be, attributed to Mo6＋ occupying regular Nb sites. Molybdenum doped lithium niobate thus is a promising candidate for all-color holographic storage applications.
