Ti:Sapphire Crystal
Titanium Doped Sapphire
is the most widely used tunable solid-state laser material. Its lasing bandwidth can support pulses < 10fs making it the crystal of choice for femtosecond mode-locked oscillators and amplifiers. The absorption band of Ti:Sapphire centers at ~ 490 nm so it may be conveniently pumped by various laser sources such as argon ion lasers or frequency doubled Nd:YAG, Nd:YLF, Nd:YVO4 lasers at ~530nm.
Applications:
1) Femtosecond Pulse Laser Material.
2) Tunable Output - 650 nm to 1100 nm.
3) Excellent Output Efficiency
4) 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.
5) Ti:Sapphire is also widely used as the pump source of OPOs to expand the tunable range.
