Ti2O3 concentration 0.06-0.26 at.%.
Right-angle cut or Brewster cut is available.
The tunable wavelengths that cover a broad range from 700 to 1000 nm make Ti:Sapphire an excellent substitute for dye lasers in many applications.
Doubling by NLO crystals such as BBO in an ultra-thin, Ti:Sapphire can be used to generate UV and DUV (up to 193 nm ) laser with ultrafast pulses below 10fs.
Ti:Sapphire is also widely used as the pump source of OPOs to expand the tunable range.

Titanium doped Sapphire (Ti:Sapphire) is the most widely used laser crystal for widely tunable and ultrafast lasers with high gain and high power outputs. The Ti:Sapphire crystals of Crysmit is grown by the method of Temperature Gradient Technique (TGT), the large-sized (Dia.30x 30mm) Ti:Sapphire crystal in high quality free of light scatter, with the dislocation density less than 102cm-2 could be provided. The TGT grown sapphire crystal is characterized by the (0001) oriented growth, high doping level (a490= 4.0cm-1), high gain and laser damage threshold.
