摘　　要：首次生长了新型激光晶体GdCa4 O (BO3) 3∶Pr简称(GdCOB∶Pr) ,测量了它的室温透过谱 ,并在 5 30nm激光激发下测量了晶体的荧光发射 ,分析并标定了Pr3+ 离子的能级跃迁对应的峰值。The transmittance spectrum of GdCOB∶Pr crystal, which was grown by using Czochraliski pulling method for the first time to our knowledge, had been measured. The fluorescence emitting exicited by a 530nm laser was recorded. The absorption peak of Pr ions was analyzed. The effect of rare earth dopant on the cut off of the crystal at UV band was disscused.
