Ti:Sapphire (Titanium doped Sapphire)

Ti3+:sapphire crystals (Titanium-doped sapphire) as an optically pumped, solid-state laser crystal is widely used in wavelength-tunable lasers.

Ti: Sapphire laser’s tunable range is 650-1100nm, and peaking at 800nm. It is one of the broadest wavelength-tunable laser crystals. The upper-state lifetime of Ti: sapphire is short to 3.2ms.

Because of the high saturation power, it’s hard to pump it by the lamp. Argon ion lasers, frequency-doubled Nd: YAG laser, etc., are usually adapted. Using self-mode-locking technology, the Ti: Sapphire laser can output laser pulse with pulse width as short as 6.5fs directly, the narrowest laser pulse of all lasers that directly output from the resonant cavity. The laser beam’s wavelength can cover broadband from blue to deep ultraviolet through frequency-double technology. Produced 193 nm laser has been used in lithography machine.
