• Introduction：

Ti:Sapphire crystal is the most widely used tunable solid-state laser material combining the supreme physical and optical properties with an extremely broad lasing range.Sapphire crystal ( known as Al₂O₃) has good thermal properties, excellent electrical properties, and dielectric properties. Besides, it has chemical corrosion resistance. It has good thermal conductivity and good chemical stability. It is resistant to high temperatures and is widely used in high-temperature-resistant infrared window materials, III-V nitrides, and various epitaxial thin film substrate materials. 

• Optical Properties：

1) Femtosecond Pulse Laser Material

2) Tunable Output-650nm to 1100nm

3) Excellent Output Efficiency

• Applications：

1) Doubling by NLO crystals such as BBO in an ultra-thin, Ti:Sapphire can be used to generate UV and DUV（up to 193nm）laser with ultrafast pulses below 10fs.

2) Ti:sapphire is also widely used as the pump source of OPOs to expand the tunable range.
