Titanium Doped

 

Ti Sapphire (Titanium doped Sapphire, Al2O3 Ti3+) has a wide range of emission band from 660 to 1050 nm, which facilitates a variety of existing and potential applications, such as tunable continuous-wave lasers, mode-locked oscillators, chirp-pulse amplifiers, thin disk oscillators/amplifiers and lidars.Moreover, the absorption band of Ti Sapphire is centered at 490 nm, ranging from 400 to 650 nm, which makes it suitable for pump sources of many different lasers, for example, argon ion, frequency doubled Nd YAG (Nd YLF), and copper vapor lasers.Because of 3.2 μs fluorescence lifetime, Ti Sapphire crystals can be effectively pumped by flash lamps in high-power laser systems.

In order to obtain good quality of Ti Sapphire crystals, the Ti3+ doping concentration has to be kept fairly low (e.g. 0.15% or 0.25%). Therefore limited pump absorption usually enforces the use of a crystal length of several millimeters, which in combination with the small pump spot size (for high pump intensity) means that a rather high pump brightness is required.Fortunately, Sapphire has also an excellent thermal conductivity, alleviating thermal effects even for high laser powers.
