摘要
用提拉法生长1%(摩尔分数,下同)In:Fe:LiNbO3(LN),2%In:Fe:LN,3%In:Fe:LN和Fe:LN晶体,配料中掺入0.03%(质量分数)Fe2O3。采用光斑畸变法测试晶体的光损伤阈值。结果表明:1%In:Fe:LN和2%In:Fe:LN晶体的光损伤阈值比Fe:LN晶体高1个数量级以上。3%In:Fe:LN晶体的光折变阈值比Fe:LN晶体高2个数量级以上。晶体的位相共轭效应测试结果表明,1%In:Fe:LN晶体的位相共轭反射率(R1=185%)高于3%In:Fe:LN晶体(R3=120%)。以3%In:Fe:LN晶体作为存储元件,1%In:Fe:LN晶体作为位相共轭镜,进行全息关联存储实验,其再现图像清晰完整,噪音小。
1% （in mole, the same below） In： Fe： LiNbO3（LN）, 2% In： Fe： LN, 3% In： Fe： LN and Fe： LN crystals, all with 0. 03% （in mass） Fe2O3 were grown by Czochralski method in the atmosphere. The photo damage threshold of In ： Fe ： LN crystals was investigated by light spot distortion method. The results indicate that the photo damage threshold is one order of magnitude higher for 1% In ： Fe ： LN and 2% In ： Fe ： LN crystals and two orders of magnitude higher for 3% In ： Fe ： LN than that of Fe ： LN crystal. The results from measuring the effect of phase conjugation of In ： Fe ： LN crystals show that the phase conjugate reflectivity R1 of 1% In ： Fe ： LN is 185%, higher than that of the 3% In ： Fe ： LN （R3 = 120%）. Holo graphic associative storage experiments were carried out by using 3% In ： Fe ： LN as the optical storage element and 1% In ： Fe ： LN as the phase con iugate mirror, and a clear and integrated image was reconstructed with a high signal-to-noise ratio.
