| 摘 要： | 系统地研究了不同掺杂浓度的Ｙｂ：ＹＡＧ晶体的光谱特性，通过吸收光谱的测量计算了晶体的吸收截面，用对易法计算了晶体的发射截面。在Ｙｂ：ＹＡＧ晶体毛坯中发现Ｙｂ＾２＋和色心，其浓度随Ｙｂ：ＹＡＧ晶体中Ｙｂ＾３＋的增加而增加。经１４００℃氧气氛退火后消失。首次用光子激发和Ｘ射线激发研究了Ｙｂ：ＹＡＧ晶体的荧光特性。

| Abstract: | The absorption and emission properties of Yb:YAG with different Yb3+ doped concentration have been studied systematically. The emission cross section has been evaluated using the absorption cross section and principle of reciprocity, which was consistent with previous reports. The absorption spectra of Yb2+ and color center were observed in as-grown Yb:YAG boules, which are removed by annealing the boules in oxygen at 1,300 degrees C for 24 h. The photon excited and X-ray excited optical luminescence of Yb:YAG were first discussed. The results indicated that Yb:YAG crystal was favourable for high-power diode-pumping. |
