Titanium Doped Sapphire (Ti: Al₂O₃ Laser Crystal

Titanium doped sapphire (Ti³⁺:Al₂O₃) is the most widely used crystal for wavelength tunable lasers and ultrashort pulse generation due to their supreme physical and optical properties with the extremely broad lasing range. It has a wide absorption range located in the green spectral region and is usually pumped with another laser with a wavelength of 514 to 532 nm.
