Study on laser property and 550nm lifetime characteristics of lithium niobate doped with magnesium and erbium

  • 摘要: 为了测试Mg:Er:LiNbO3晶体的光损伤阈值和红外光谱,采用Czochralski技术生长出优质的Mgx:Ery:LiNbO3(x=0.02,0.04,0.06,0.08,y=0.01(摩尔分数))晶体。通过实验得出Mg(0.06):Er:LiNbO3和Mg(0.08):Er:LiNbO3晶体抗光损伤阈值比LiNbO3晶体提高2个数量级以上,且它们的红外光谱OH-吸收峰移到3535cm-1附近;在波长510nm~580nm范围内得到Mg:Er:LiNbO3晶体稳态发射谱。结果表明,Mg2+浓度增加抗光损伤能力增加,掺进摩尔分数为0.04的MgO是Mg:Er:LiNbO3晶体寿命最长的晶体。
    Abstract: In order to measure the photo damage threshold and infrared spectra of Mg:Er:LiNbO3 crystals,the high quality Mgx:Ery:LiNbO3(x=0.02,0.04,0.06,0.08,y=0.01(mole fraction)) crystals were grown by Czochralski technique.The experiment indicated that the photo damage resistance ability of Mg(0.06):Er:LiNbO3 and Mg(0.08):Er:LiNbO3 crystals improved the two orders magnitude over higher than that of LiNbO3 crystals and their OH-absorption peak of infrared spectra shifts to 3535cm-1 nearby.The experiment gained the steady state shoot spectra of Mg:Er:LiNbO3 crystals in wavelength 510nm~580nm finding doped with mole fraction 0.04 of MgO.The results showed that the Mg2+ concentration increased the photo damage resistance ability increased and the lifetime of Mg:Er:LiNbO3 crystal doped with mole fraction 0.04 of MgO was the longest.
