选择中频电磁感应加热提拉法生长出了透明、基本无散射和气泡、无包裹物的高质量的铥(Tm)取代钇（Y）的原子数分数为2%的Tm:YLiF4（YLF），并采用X射线衍射（XRD）法对晶体进行了物相分析。测试TmYLF晶体的吸收光谱并计算了Tm离子对不同波长的吸收系数和吸收截面。同时测定其荧光光谱并分析了3H4－3F4和3F4－3H6跃迁产生的发射峰。对TmYLF晶体进行了激光实验，当输入功率为160 W时，获得了54.4 W的激光输出，斜率效率为35.6%，最大光光转换效率为31.2％。

High optical quality 2% number fraction of thulium replacemented yttrium atoms Tm:YLiF4 (YLF) crystal is successfully grown by the Czochralski technique with the medium frequency induction heating furnace. The structure of TmYLF crystal is determined by the precise X ray diffraction (XRD) measurement. And the spectral properties of TmYLF crystal are studied and analyzed by absorption and fluorescence spectra. Absorption coefficient and absorption section of Tm ion at different wavelengths are calculated. At room temperature, TmYLFslabs made by 2% thulium-doped single crystal are end-pumped by a laser diode stack at wavelength of 793 nm. Laser output of 54.4 W continuous wave power at 160 W input power is achieved, corresponding to an optical efficiency of 31.2%.
