Large-sized titanium doped sapphire (TiAl2O3) 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 TiAl2O3 is measured in 200~1100 nm, and a figure of merit (FOM) is evaluated above 240. The laser quality of TiAl2O3 in both static and single pulsed amplifier system are outstanding without distortion, and the amplified output energy achieves international level.
