Product Info
A dispersive mirror, also known as a Gires–Tournois interferometer (GTI) mirror, is an optical standing-wave resonator designed for generating chromatic dispersion. These mirrors are used mainly for pulse compression in Yb:YAG and Yb:KGW femtosecond lasers, but can be optimized for other wavelengths, such as in Ti:Sapphire laser systems.
Compared to prism or grating pulse compression systems, dispersive thin-film mirrors exhibit lower losses and lower sensitivity to mechanical misalignment errors, enabling a simpler and more stable laser.
We design standard items for most common laser wavelengths and dispersion values, but Altechna also offers custom-designed dispersive mirrors in terms of wavelength, size and GDD. It is worth mentioning that our dispersive mirrors are coated with sputtering technology, ensuring a high level of performance and durability.
