摘　　要：本文研究了Ｎｄ：ＹＡＧ晶体由于小面的生长而产生核心与侧心的机理。讨论了熔体生长Ｎｄ：ＹＡＧ晶体的固液界面形状和温度梯度及小面生长的内在联系；探讨了消除侧心、减小核心的技术途径；并生长出无侧心、小核心Ｎｄ：ＹＡＧ晶体。The mechanisms of producing central core and lateral core through growth with facets in YAG crystals were discussed. The relations between solide liquild interface shape and temperature gradient in the melt and facets growth were described. The technical methods of eliminating lateral core and reduction central core in crystal were revealed. And the lateral core free and small central core Nd:YAG crystals were grown.
