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.
系统研究了不同Yb3+掺杂浓度的Yb:YAG的吸收和发射特性。利用吸收截面和互易原理评估了发射截面，结果与先前报道一致。在生长态的Yb:YAG晶锭中观察到了Yb2+和色心的吸收光谱，通过在1300℃的氧气中对晶锭进行24小时退火可消除这些吸收光谱。首次讨论了Yb:YAG的光子激发和X射线激发光致发光。结果表明，Yb:YAG晶体有利于高功率二极管泵浦。
