摘要
报道了利用ＣＣＤ测试ＬｉＮｂＯ３条波导光损伤的实验结果。发现各种传向都存在不同程度的光损伤。加热可大部分消除光损伤，掺入ＭｇＯ也可提高条波导的抗光损伤性能。
The experimetal observation of optical damage of channel waveguides onLiNbO3 substrate by CCD is reported. We found that optical damage was propagationdirection dependent.The optical damage can be partly erased by heating the sample.Theresistance against optical damage of MgO doped LiNbO3,i.e.MgO:LiNbO3,is strongerthan that of pure LiNbO3.
