Titanium doped Sapphire (Ti:Sapphire) is the most widely used laser crystal for widely tunable and ultrashort pulsed lasers with high gain and power outputs. CASTECH possesses the advanced growth method of Temperature Gradient Technique (TGT), and it supplies large-sized (Dia.30x30mm) Ti:Sapphire crystal in high quality free of light scatter, with the dislocation density less than 102cm-2. The TGT grown sapphire crystal is characterized by the (0001) oriented growth, high doping level (α490 = 4.0cm-1), high gain and laser damage threshold.
? 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.
