【Abstract】 In the range of 30℃ to 130℃, the mechanism for the anomalous phenomena of LiNbO₃ crystals has been proved similar to that for the optically induced change of refractive indices. The anomalous phenomena result from thermally excited electrons in the point defect of crystals. According to the experiment result, a model of thermal excitation is proposed by the authors. The anomalous phenomena of LiNbO₃ can be deduced from the model. Several problems occurred in experiments which were difficult to explain in the past are discussed in the paper.更多还原
