测量了Ｔｍ３＋和Ｈｏ３＋离子的吸收谱以及Ｃｒ３＋离子在ＹＡＧ单晶光纤中的Ｒ荧光线的寿命．用Ｄｅｘｔｅｒ理论讨论了Ｃｒ３＋离子的能量转移效率。结果表明Ｃｒ３＋→Ｔｍ３＋的能量转移效率比Ｃｒ３＋→Ｈｏ３＋的大．
The absorption spectra of Tm3 + and Ho3 + ions and the lifetime of the R fluorescence line of Cr3 + ions in a YAG single crystal fiber were measured. The Dexter theory is used to discuss the energy transfer efficiency of Cr3 + ions. The results show that the energy transfer efficiency of Cr3 + → Tm3 + is larger than that of Cr3 + → Ho3 +.
