Titanium doped sapphire (Ti3+:Al2O3) is a popular tunable laser
crystal for femtosecond solid-state lasers in the world. It is
famous for its supreme thermal and optical properties. It is also
known as the best material for ultrashort pulse generation with
wide range of emission band from 660 to 1050 nm which is red and
near-infrared light. In addition, high repetition rate oscillators,
Chirped-pulse laser amplifiers and Wavelength tunable CW lasers are
the common usage.
As for femtosecond lasers, it is mainly applied to scientific
research, biological imaging, life sciences and precision material
processing. This kind of laser systems offer a high average power
and a broad tuning range among others. And the spectra are well
suited for amplifier seeding, especially for Optical Parametric
Chirped Pulse Amplifiers (OPCPA), or equipped in pump experiments.
What’s more, this laser has numerous imaging applications including
Attosecond Science and High Harmonic Generation, Two-Photon
Fluorescent Imaging, and so on.
