Titanium-sapphire laser
Videos
A titanium-sapphire laser is a tunable laser which emits red and near-infrared light in the range from 650 to 1100 nanometers. This type of laser is mainly used in scientific research because of its t

A Ti:Sapphire crystal in the centre of a multipass amplifier Quantronix Odin is pumped by 5W green beam (faintly visible coming from right), amplifies femtosecond pulses that pass it several times under different angles (invisible on the photo) and loses part of energy as red fluorescence light.
Femtosecond pulses generate multiple angle-resolved colour patterns when focused; note their fan-out angle is even higher than that of the focused las

Titanium-sapphire laser
…first constructed and invented in June 1982 by Peter Moulton at the MIT Lincoln Laboratory. Titanium-sapphire refers to the lasing medium, a crystal of sapphire (Al2O3) that is doped with Ti3+ ions. A Ti:sapphire laser is usually pumped with another laser with a wavelength of 514 to 532 nm, for which argon-ion…
