Ti:Sapphire (Titanium sapphire)
Ti:Sapphire crystal product, also known as titanium doped sapphire crystal, with the chemical formula of Ti3+:Al2O3. It is a transition metal doped laser crystal with good comprehensive performance. As an optically pumped solid-state laser crystal, Ti-doped sapphire is widely used in wavelength tunable lasers. The tunable range is 650-1100 nm and the peak value is 800 nm. It is the widest wavelength tunable laser crystal. Ti3+ ions have very large gain bandwidth, which opens the possibility of obtaining very wide wavelength tunability in short pulse lasers. The upper state lifetime of Ti: sapphire is as short as 3.2 μs. because …
