应用同步辐射X射线形貌术对坩埚下降法生长的Nd:SGG晶体的缺陷进行了研究。观察到该晶体中存在较为明显的镶嵌结构晶界缺陷和位错缺陷
并分析了上述缺陷的形成原因。对提高Nd:SGG晶体质量、改进生长工艺具有一定的参考价值。
A synchrotron radiation white-beam topography experiment has been performed to investigate the defects of Nd:SGG laser crystals grown by Bridgman method for the first time. Clear images of some defects
such as boundaries and dislocations were observed. The formation mechanism of these defects was discussed. It’s anticipated that the results of this work will be useful for optimizing the growth conditions of Nd:SGG laser crystals.
