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.

A multi-layer dielectric coating offers a high reflectance of 99.8% from 700 to 900 nm.
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.
These chirped mirrors offer very low third order dispersion (cubic term) across the specified 700 to 900 nm wavelength range.
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).
These mirrors are ideal to be used with Spectra-Physics Tsunami®, Mai Tai® or Element 2TM lasers.
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.
