Titanium doped Sapphire (Ti:Sapphire) is a versatile crystal for scientific and research applications. It combines the excellent thermal, physical and optical properties of sapphire with the broadest tunable range of any known laser material. Short, femto-second pulses can be produced successfully across the tunable range making Ti:sapphire ideal for ultra-fast spectroscopy.
Bluebean Optical supplies Ti:Sapphire in a broad range of compositions and sizes, with excellent figures of merit (FOM) and optical quality. Laser output can be can be generated over the entire spectrum from 650 nm to 1100 nm. Frequency doubling the output provides tunability across the blue-green region of the visible spectrum.
