Ti:SAPPHIRE
Description:
Titanium Doped Sapphire Crystal (Ti:Sapphire, Ti:Al2O3), is the most widely used laser crystal for widely tunable and ultrashort pulsed lasers with high gain and high power outputs.
Applications:
l 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;
l 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;
l Ti:Sapphire is also widely used as the pumping source of OPOs greatly to expand the tunable range.
