| 摘 要： | The effect of melt pretreatment of Ce~(3 ): YAP and (Ce~(3 ) Nd~(3 )): YAP and their growth ambient gases on the quality of the crystals are described. Firstly, a superheating pretreatment of YAP melt is adopted in a nitrogen atmosphere containing a little oxygen to eliminate carbon; then the YAP melt is superheated in a reduction atmosphere to fully reduce Ce~(4 ) ions into Ce~(3 ) ions in the melt. Finally, in a growth atmosphere of pure nitrogen, high quality Ce~(3 ): YAP and (Ce~(3 ) Nd~(3 )): YAP single crystals with high Ce~(3 ) concentration with only few light scattering centers were grown.

| Abstract: | The effect of melt pretreatment of Ce3 :YAP and (Ce3 Nd3 ) :YAP and their growth ambient gases on the quality of the crystals are described. Firstly, a superheating pretreatment of YAP melt is adopted in a nitrogen atmosphere containing a little oxygen to e-liminate carbon; then the YAP melt is superheated in a reduction atmosphere to fully reduce Ce4 ions into Ce3 ions in the melt. Finally, in a growth atmosphere of pure nitrogen, high quality Ce3 :YAP and (Ce3 Nd3 ) :YAP single crystals with high Ce3 concentration with only few light scattering centers were grown. |
