| Abstract: | The growth procedure and crystal form of hydrothermal KTP are reported in this article.Some defects in the hydrothermally grown KTP crystal were researched.The macroscopic defects of hydrothermal KTP crystal are mainly twin and coalescence crystal,growth spine,cracks and inclusions.The causes were also discussed. Some suggestions on improving the techniques of the crystal growth of KTP crystal are given at the end of this article to improve the quality of the grown crystals,such as promoting the purity of materials and reagents,minimizing the dimensions of seed crystals and choosing the hang direction of seed crystals,and so on.Parallel to(011) seed crystals can grow pure KTP crystals,and these crystals have a high efficient in the laser device. |
