About Ti+ sapphire crystal
Ti: sapphire (Titanium doped Sapphire, Al2O3:Ti3+) is used for making ultra short pulse solid-state or wavelength tunable lasers. Ti:sapphire lasers are also very convenient e.g. for pumping test setups of new solid-state lasers
(e.g. based on neodymium- or ytterbium-doped gain media), since they can easily be tuned to the required pump
wavelength and allow one to work with very high pump brightness due to their good beam quality and high output power of typically several watts.
Ti: Sapphire crystals are active media for highly efficient tunable solid-state lasers. They demonstrate good operation in the pulsed-periodic, quasi-CW and CW modes of operation. Ti:Sapphire is a 4-level, Vibronic laser with fluorescence lifetime of 3.6 µm. The peak of the absorption band is 490 nm which makes it an excellent material for pumping with a variety of sources operating in the green-argon ion, copper vapour, frequency-doubled Nd:YAG, and dye lasers are routinely used. Crystals have also been flashlight pumped by lamps designed to allow short fluorescence lifetime. These factors and broad tunability make it an excellent replacement for several common dye lasing materials. The crystals are grown using the Czochralsky and the Ciropolous techniques.
