Ti:sapphire lasers (also known as
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 in 1982.
