800nm Highly-Dispersive Ultrafast Mirrors

Reflection >99.8% (p-polarization) between 780 - 830nm
Group Delay Dispersion of -1300fs² at 5° AOI
Ideal for Pulse Compression of Ti:sapphire Ultrafast Lasers
Ultrafast Chirped Coating

800nm Highly-Dispersive Ultrafast Mirrors feature an optimized multilayer ultrafast chirped coating based on dispersive optical interference that provides a low group delay dispersion (GDD) and high reflectance. At their design angle of incidence (AOI) of 5°, these mirrors have a GDD of -1300 fs² and a minimum reflectivity of 99.8% for p-polarization. The highly-dispersive design of these ultrafast mirrors offers control of third and higher order dispersions, and provides high beam stability. 800nm Highly-Dispersive Ultrafast Mirrors are ideal for pulse compression and dispersion compensation of ultrafast pulses, such as from Ti:sapphire lasers. Standard imperial sizes are available, featuring fused silica substrates, with 10-5 surface quality and λ/10 irregularity.
