摘要
采用提拉法生长的Nd:LuVO4 晶体是一种适合二极管泵浦的新型激光晶体,运用化学腐蚀结合光学显微术和同步辐射白光X射线形貌术对Nd:LuVO4 晶体缺陷进行观察,结果表明:晶体的主要缺陷为位错和小角晶界。利用高分辨X射线衍射仪进一步验证了这一结果。并初步讨论了缺陷形成的原因。
A new laser crystal Nd:LuVO4 was grown by Czochralski method. The growth defects in the Nd:LuVO4 crystals were observed by optical microscopy combined with white-beam synchrotron radiation topography. It is shown that the main growth defects in the Nd:LuVO4 crystals are dislocations and low-angle grain boundaries. The result was confirmed furthermore by high resolution X-ray diffractometry. In addition, the formation mechanisms of these defects in Nd:LuVO4 crystal were discussed.
