Ti:sapphire laser has played an important role in scientific
and industrial applications since its advent in 1982.
Ti:sapphire has broadband absorption centered in the blue-
green wavelength region (400–600 nm) and associated
broadband emission (650–1150 nm) at red-near IR
wavelengths,which make it one of the best materials for
ultrashort pulses generation and wavelength tuning.
Ti:Sapphire(Al2O3:Ti3+) - titanium-doped sapphire crystals combine supreme physical and optical properties with broadest lasing range, Ti:Sapphire's indefinitely long stability and useful lifetime added to the lasing over entire band of 660-1050 nm challenge "dirty" dyes in variety of applications. Medical laser systems, lidars, laser spectroscopy, direct femtosecond pulse generation by Kerr-type mode-locking - are few of existing and potential applications..
The absorption band of Ti:Sapphire centered at 490 nm, making it
suitable for variety of laser pump sources including argon ion laser, frequency
doubled Nd:YAG, and LD laser. Ti:Sapphire crystal
has a fluorescence lifetime of 3.2 microseconds, allowing them to be
effectively pumped by short pulse flashlamps in high-powerlaser systems.
