Attention! You can customise this product to your needs.
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 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.
varna Reflectivity up to 99,9%
varna Central wavelength tolerance up to 1%
varna GDD values ranges from 100 to 1500 fs2 for Yb:KGW, Yb:YAG laser type coatings according to customer specifications
varna Calculated and measured GDD curves are supplied with every batch
