Low GDD Ultrafast Broadband Mirrors


Are these standard mirrors suitable for my Yb: KGW or Ti: Sapphire laser? Will these mirrors maintain the temporal characteristics of the laser beam? Will they handle high peak intensity?

Low GDD Ultrafast Mirrors are designed to handle high peak powers, provide a reflectance greater than 99.8% and keep the GDD slightly negative. This makes these mirrors ideal for femtosecond laser systems, like the Ti: Sapphire, where pulse broadening is a concern.


Absolute reflectance Rs>99.8% and Rp>99.8%

Despite broadband design, low GDD ulftrafast mirrors maintain a high reflectivity greater than 99.9%.

Compensated for Group Delay Dispersion (GDD)

Coatings are designed in a way that the GDD is slightly negative. This prevents pulse broadening and helps to maintain high peak power.

Wide spectral bandwidth

OPTOMAN designs mirrors to steer beams with over 99.8% reflection across the wide wavelength ranges, such as from 650 nm to 1200 nm.

Wide cone of AOI

Should you need mirrors operating at a wide range of angles, OPTOMAN is ready to design broadband mirrors with a wide cone of AOI.
