Femtoline Low GDD Ultrafast Mirrors are specially designed for femtosecond laser applications. They offer a broad operating wavelength range and exhibit linear phase versus frequency characteristics, ensuring low group delay dispersion (GDD). The mirrors feature a single-layer dielectric coating that maintains a consistent phase shift over the entire operating wavelength region.

 For optimal performance, it is recommended to use these mirrors with s-polarized beams, as they provide higher reflection, broader operating regions, and lower pulse distortion for s-polarization compared to p-polarization with the same dielectric coating. These mirrors are suitable for high-power laser applications operating in the UV region and are compatible with fundamental Ti:Sapphire and Yb:KGW/KYW lasers and their harmonics.
