- Description
- Standard specifications
Ultrafast low-GDD mirrors provide high reflectance while minimizing group delay dispersion (GDD). Their performance is based on precisely engineered dielectric thin-film coatings, which utilize optical interference effects to achieve both high reflectivity and controlled dispersion. Deposited on high-purity fused silica substrates, these coatings ensure minimal pulse broadening, making them ideal for femtosecond and picosecond laser systems.
