Titanium sapphire Laser

Ti:sapphire lasers (Ti:Al2O3 lasers, titanium-sapphire lasers, or Ti:sapphs) are tunable lasers which emit red and near-infrared light in the range from 650 to 1100 nanometers. These lasers are mainly used in scientific research because of their tunability and their ability to generate ultrashort pulses. Lasers based on Ti:sapphire were first constructed and invented in June 1982 by Peter Moulton at the MIT Lincoln Laboratory


Lasers based on vibronic crystal Ti:Sapphire (also known as Ti:Al2O3 lasers, titanium-sapphire lasers, Ti:sapp, Ti:S, Ti:Sa, Ti-Sapp or simply Ti:sapphs) are used widely in research as they are tunable and capable of ultra-short pulses from a few picoseconds (ps) to tens of attoseconds (as), typically tens of femtoseconds (fs) in duration. Ti:Sapphire preferentially emits in  the region of 800 nm, but the crystal is capable of a tuning range spanning 650 nm to 1100 nm. Often referred to as an oscillator, this laser is created by pumping the titanium ion doped sapphire crystal with a laser at a shorter wavelength.


Titanium-sapphire refers to the lasing medium, a crystal of sapphire (Al2O3) that is doped with titanium ions. A Ti:sapphire laser is usually pumped with another laser with a wavelength of 514 to 532 nm, for which argon-ion lasers (514.5 nm) and frequency-doubled Nd:YAG, Nd:YLF, and Nd:YVO lasers (527-532 nm) are used. Ti:sapphire lasers operate most efficiently at wavelengths near 800 nm.

2940nm Laser

Diode laser VS Er:YAG laser Er:YAG lasers typically emit light with a wavelength of 2940 nm. the output of Er:YAG lasers is also absorbed by hydroxyapatite, which makes it a good laser for cutting bone as well as soft tissue.the output of an Er:YAG laser is strongly absorbed by water. This fact limits the use of this laser in surgery.Er:YAG lasers are far less common than their relatives diode laser. Diode laser is portable in size,affordable,very good for soft tissue surgery,the limit is can not applied to hard tissue
