The Ti:sapphire crystal is the bright red light source on the left. The green light is from the pump diode]] '''~~Ti:~~Titanium-sapphire lasers''' (also known as '''Ti:sapphire lasers''', '''Ti:Al<sub>2</sub>O<sub>3</sub> lasers'''~~, '''titanium-sapphire lasers''',~~ or '''Ti:sapphs''') are [[tunable laser]]s which emit [[red]] and [[infrared\|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 pulse]]s thanks to its broad light emission spectrum. Lasers based on Ti:sapphire were first constructed and invented in June 1982 by Peter Moulton at the [[MIT Lincoln Laboratory]].<ref>{{cite journal \|doi=10.1364/JOSAB.3.000125\|title=Spectroscopic and laser characteristics of Ti:Al<sub>2</sub>O<sub>3</sub>\|journal=Journal of the Optical Society of America B\|volume=3\|pages=125–133\|year=1986\|last1=Moulton\|first1=P.

A Ti:sapphire laser is usually [[Laser pumping\|pumped]] with another laser with a wavelength of 514 to 532 nm, for which [[argon]]-[[ion laser]]s (514.5 nm) and [[Second harmonic generation\|frequency-doubled]] [[Nd:YAG]], [[Nd:YLF]], and [[Neodymium-doped yttrium orthovanadate\|Nd:YVO]] lasers (527–532 nm) are used. They are capable of laser operation from 670 nm to {{formatnum:1100}} nm wavelength.<ref name="steele91">{{cite journal\|last1=Steele\|first1=T.R.\|last2=Gerstenberger\|first2=D.
