Gires-Tournois interferometer, Chirped Mirror, GTI

Manufacturer's part number :


Manufacturer Altechna


Description :

A Gires-Tournois interferometer (GTI) is an optical standing wave resonator designed for generating chromatic dispersion. GTI mirrors are used mainly for pulse compression in Y b:YAG, Yb:KGW femtosecond lasers, but can be optimized for other wavelengths, for example Ti:Sapphire laser system. Compared to prism or grating pulse compression systems GTI thin film mirrors exhibits lower losses and sensitivity to mechanical misalignment errors, thus enabling higher output power and stability of laser system.
