When transmitting ultrafast laser beams through optical components, pulses become chirped and broadened. Our chirped mirrors have negative group delay dispersion to compensate for these pulse broadening effects.
- Low phase distortion with negative GDD
- RP>99.8% @ 700–900 nm, 5° AOI
- Compensate for pulse broadening effects in ultrafast beams
- Polished back surface allows transmission at other wavelengths See All Features

Features
Compensate for Pulse Broadening
Our chirped mirrors have negative group delay dispersion to compensate for ultrafast pulses that have been broadened by transmission through optical components. The degree of compensation may be tuned by reflecting beams multiple times between two or more chirped mirrors.
Clear Quadrant Mirror Mounts Application
To get the most our of your chirped mirrors, it is imperative that you mount them for optimized performance. Mounting into Newport's patented clear quadrant mounts – such as SN100C-F2K or U100-A2K – will create the closest separation between two mirrors to allow for a large number of bounces between elements (U.S. Patents: 6,304,393; 5,930,057, and 6,016,230).
Fused Silica Substrates
Fused Silica is synthetic amorphous silicon dioxide of extremely high purity. This non-crystalline, colorless silica glass combines a low content of inclusions with high refractive index homogeneity, a very low thermal expansion coefficient, and excellent transmittance in the wavelength regime from UV to NIR. As a result, these mirrors will perform better with temperature fluctuations and is ideal for high-energy laser applications due to its high energy damage threshold.
