摘要
用 2种方法测量BTO晶体的吸收系数随光强变化关系 ,结果表明 ,室温下BTO晶体的吸收系数对光强的依赖关系很大 。
The intensity dependence of the absorption coefficient of BTO is measured with two methods.The result indicates that the absorption coefficient of BTO depends greatly on the intensity of laser,which is indicative of BTO with deep and shallow centers.
