摘要：

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:Al2O3 is measured in 200~1100 nm, and a figure of merit (FOM) is evaluated above 240. The laser quality of Ti:Al2O3 in both static and single pulsed amplifier system are outstanding without distortion, and the amplified output energy achieves international level.
