Femtoline Low GDD Ultrafast Mirrors SKU: 037-0400-i0
Laser mirrors for femtosecond applications are designed to have a broad operating wavelength range and linear phase versus frequency characteristics (low group delay dispersion (GDD)). The coating is a single layer dielectric and has no phase shift over the operating wavelength…
