摘要
本文报告了用光学方法研究高增益、低阈值的新型自激活自倍频的四硼酸铝钇钕(NYAB)晶体的缺陷。这些缺陷包括位错、异质结构夹层、双晶、云层、包裹体、开裂等。分析了这些缺陷的成因,提出了减少缺陷的措施。
In this paper the defects in a new type of high-gain, low-threshold, self-active, self-frequency-doubling NYAB crystal are investigated by optical methods. These defects include dislocations, heterojunction layer twins, clouds, inclusions, and cracks. The causes of defect formations are analyzed, and the ways of reducing de fects are suggested.
