The Ti: Sapphire Laser
Julien Klein
Since their invention in the early 1980s, titanium-doped sapphire (Ti:Al2O3 or Ti:sapphire) lasers and amplifiers have enabled countless applications in fundamental research in physics, biology and chemistry. Today, they play an important role across a wide range of photonics applications, including multicolor ultrafast spectroscopy, multiphoton deep-tissue imaging, terawatt and petawatt physics, and “cold” micromachining.
