PeakPower Low-GDD Ultrafast Dielectric Mirror, 920nm, 45° AOI, 12.7mm Dia., 6.35mm Thick

Product Details High Femtosecond Laser Damage Threshold exceeding 0.75J/cm 2 for 25fs Pulse Duration at 920nm > 99.5% Reflectivity with Near Zero Group Delay Dispersion Platinum-Level 2024 Laser Focus World (LFW) Innovators Award TECHSPEC PeakPower High LDT Low GDD Ultrafast Mirrors utilize an innovative design approach to maximize laser damage threshold for ultrafast pulses. These mirrors boast a near 0fs 2 GDD over a broad spectral bandwidth, making them suitable for the most demanding ultrafast applications. A 45° angle of incidence makes them perfectly suitable as turn mirrors in advanced ultrafast laser systems. TECHSPEC PeakPower High LDT Low GDD Ultrafast Mirrors’ high reflectivity ensures minimal loss while maintaining ultrashort pulse durations. The outstanding high laser damage threshold (LDT) values exceeding 0.75J/cm 2 for 25fs Pulse Duration at 920nm for these mirrors ensures they will perform even under exceptionally high ultrafast pulse energies.
