| 摘 要： | 采用提拉法生长了掺杂浓度分别为4、8与10at%的Tm:YAP晶体. 测定了Tm3+在YAP基质中的分凝系数为0.88. 采用同步辐射的方法研究了Tm:YAP晶体的生长条纹和结构应力缺陷. 晶体的吸收峰位于694和795nm; 荧光谱峰值在2.0μm附近, 因此Tm:YAP晶体有望成为一种新型的适合LD泵浦的中红外激光材料. |

| Abstract: | YAP single crystals doped with 4at%, 8at% and 10at% Tm3+ ions were grown by the Czochralski method with MF induction heating. The segregation coefficient of Tm3+ ion in YAP crystal measured by X-ray fluorescence spectrum technique is about 0.88. Growth striation and structural stress were determined by synchrotron radiation white-beam topography (SRWBT). The absorption spectrum shows two peaks with wavelength of 694nm and 795nm, and the fluorescence peak is about 2.0μm, which suggest that Tm:YAP is one of the most promising mid-infrared laser crystals. |
| Keywords: | Tm:YAP crystal Czochralski method segregation coefficient spectral characteristic |
