摘要：
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 2.0 mu m, which suggest that Tm:YAP is one of the most promising mid-infrared laser crystals.
