Titanium sapphire (titanium-doped sapphire, Al2O3 Ti3+) has a wide emission band from 660 to 1050 nm.

This contributes to a variety of existing and potential applications. Examples include tunable continuous wave lasers,

mode-locked oscillators, chirped pulse amplifiers, thin-plate oscillators/amplifiers, and laser detectors and meters.

In addition, the absorption band of titanium gemstone is centered at 490 nm and between 400 and 650 nm.

It is suitable for pumping sources of various lasers, such as argon ion, frequency doubled NdYAG (Nd-YLF) and copper vapor laser.

Due to the 3.2μs fluorescence lifetime, Ti:Sapphire crystals can be effectively used as high-power flash-pumped laser systems.
