SHG study for anomalous properties of LiNbO3 crystal near 75 ℃
The intensity of SHG vs temperature scanning curve of LiNbO3 crystal have been measured with an acostic-optical Q-switch Nd3+:YAG laser. The change of coherence length of Maker finger was used to research the anomalous properties of LiNbO3 crystal. Experiment result showed the coherencelength broadening anomalously near 75℃. This anomalous phenomena may be attributed to the anomalous variety of refraction index owing to some ions movement in crystal near 75 ℃.
