Titanium-doped sapphire (Ti:sapphire) crystals combine supreme physical and optical properties with broadest lasing range. It'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 - there are few of existing and potential applications
.
The absorption band of Ti:Sapphire centered at 490 nm makes it suitable for variety of laser pump sources - argon ion, frequency doubled Nd:YAG and YLF, copper vapour lasers. Because of 3.2 µs fluorescence lifetime Ti:Sapphire crystals can be effectively pumped by short pulse flashlamps in powerful laser systems.
CLaser have successfully produced large-sized (Dia.120x80mm) Ti:Sapphire by using the growth method of Temperature Gradient Technique (TGT). TGT is characterized by the capabilities of growing (0001) oriented sapphire with high doping level (a490=7.5cm-1) high gain, and high laser damage threshold. Pulsed, quasi-cw, cw, ps and fs lasing with high efficiency have been realized using TGT grown Ti: Sapphire. It can also meet current application such as in large aperture amplifiers for high power generation and laser fusion etc.
