Titanium Sapphire

Titanium doped sapphire(Ti3+:Al2O3) is widely used for tunable lasers and femtosecond solid-state lasers.It was first used as a gain medium in 1986, and till now, it is still the best material for ultrashort pulse generation. The substrate-sapphire has good physical and optical properties. High thermal conductivity and good alleviating thermal effects provide the usability for high power laser.
