The 10Q20UF.42PAIR Ultrafast Chirped Matched Pair of Mirrors for Ultrashort Pulses is a 1.0 inch (25.4 mm) diameter, 10.0 mm thick, laser chirped and is optimized for 700 — 890 nm. When transmitting an ultrashort pulse laser beam through a number of optical components, the pulse will spread and become chirped. This matched pair of mirrors are the solution to compensate for pulse broadening effects. These mirrors provide a negative group delay dispersion to the incoming laser beam with every bounce off the surface. By setting up a two or three mirror configuration, the laser beam can bounce back and forth between the mirrors many times to compensate for pulse dispersion effects. These mirrors can be mounted into Newports patented clear quadrant mounts to 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). The high reflectivity of the mirror will preserve the laser beam intensity. Designed to reflect over 99.5% from 700 to 890 nm, this mirror is ideal to use with Spectra-Physics Tsunami, Spitfire Pro, or Mai Tai lasers. Careful thin film design and advanced coating processes result in a mirror with maximum reflectivity, high bandwidth and negative Group Delay Dispersion. This chirped mirror set is optimized for use with 10 fsec pulses and shorter.
