Ultrafast Mirrors
Ultrafast mirrors have high laser-induced damage thresholds, greater reflectance, and low Group Delay Dispersion (GDD) effects on the ultrashort pulses. They are utilized in the beam steering applications with Ti:Sapphire, Yb:YAG, Yb:KGW and Er:Fiber laser fundamental wavelengths as well as their harmonics. Ultrafast laser mirrors are used in various fields including spectroscopy, material processing, and the medical industry.
