14DM-GTI - Gires-Tournois Interferometer Mirrors
Model: GTI
品牌:Standa

產品特色Features

Reflectivity up to 99.9%

Central wavelength tolerance up to 1%

GDD values ranges from 100 fs² to 1500 fs² for Yb:KGW, Yb:YAG laser type coatings

GDD - Group Delay Dispersion

Gires-Tournois interferometer (GTI) is an optical standingwave resonator designed for generating chromatic dispersion. GTI mirrors are used mainly for pulse compression in Yb: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.
