Ultrafast Enhanced Silver Mirror, 750-1000nm
Tuniu ultrafast enhanced silver film mirrors are engineered for high-power-density and short-pulse laser applications, ideal for use in all types of ultrafast laser systems. These mirrors feature a dielectric-enhanced silver coating deposited on UV fused silica substrates, delivering outstanding optical performance across the 750–1000 nm operating wavelength range. Within the working band, the mirrors provide reflectivity greater than 98.5% and an extremely low group delay dispersion (GDD) of less than 30 fs². Combining low dispersion with a high laser-induced damage threshold, the mirrors can withstand long-term high-power laser irradiation while maintaining excellent stability and reliability during high-speed laser transmission. They serve as essential optical components for optimizing the overall performance and operational stability of ultrafast laser systems.
