The UV photorefraction of Zr-doped lithium niobate (LN:Zr) was investigated. The experimental results show that LN:Zr crystals have high resistance against photorefraction in the UV region as well as in the visible range and can withstand a UV light intensity of above 10(5) W/cm(2). According to the fitting results of erasing curves with UV and green light, a two-center O(2-/-)-defect model was suggested. Our results indicate that LN:Zr is an excellent candidate for optical damage resistance from the UV to the visible spectrum.
研究了掺锆铌酸锂（LN:Zr）的紫外光光折变。实验结果表明，LN:Zr 晶体在紫外光区和可见光区都具有很高的抗光折变能力，能承受超过 10(5) W/cm(2)的紫外光强度。根据紫外光和绿光消光曲线的拟合结果，提出了一个双中心 O(2-/-)-缺陷模型。我们的结果表明，LN:Zr 是一种从紫外到可见光谱范围内具有优异抗光损伤能力的候选材料。
