摘　　要：阐述了温梯法生长大口径、高质量的掺钛蓝宝石晶体。生长的钛宝石在300~900nm波段具有较好的光学吸收特性,通过测定晶体横截面不同位置处的吸收系数来表征掺杂浓度的均匀性。测定钛宝石在200~1100nm波段的透射率,计算品质因素（FOM）值在240以上。钛宝石晶体的静态和单发放大的光斑质量较高、无畸变,其抽运激光的放大输出能量达到国际相同规格钛宝石的同等水平。
Large-sized titanium doped sapphire （Ti：Al2O3） crystal with high quality is grown by the temperature gradient technique （TGT）. The as-grown crystal has an excellent absorption features in 300~900 nm. The doping uniformity of titanium is demonstrated by measuring the absorption fluctuation in cross-section of the crystal. The transmittance of Ti： A2 03 is measured in 200--1100 nm, and a figure of merit （FOM） is evaluated above 240. The laser quality of Ti： Al2 03 in both static and single pulsed amplifier system are outstanding without distortion, and the amplified output energy achieves international level.
